A RELAX NG schema document is validated before pattern interpretation
in three layers: the section-3 grammar check (vocabulary, attributes,
arity, text, QNames, datatypeLibrary URIs, hrefs, 4.16 excepts, xmlns
prohibitions), compiler checks (4.17 combine rules, unresolved refs,
parentRef scope, startless grammars, include/externalRef cycles and
overrides, grammar-checked loaded documents, unknown datatypes,
built-in-library params), and the 4.19/7.1-7.4 restrictions over the
compiled algebra after 4.20/4.21 normalization (prohibited paths,
content types, duplicate attributes via representative-name overlap,
infinite-class attributes outside oneOrMore, interleave constraints),
with recursion detection deliberately before normalization. Incorrect
schemas: 213 compiling down to 7, all the pre-Fifth-Edition name-class
class (count asserted). Two leniency tests updated to spec behavior.
Closes#131
A value of type QName compiles to its (namespace, local) pair via the
schema's xmlns/ns scope; the derivative engine threads the instance
element's in-scope bindings to value comparison in both the tree walk
and the streaming state (frames carry their bindings), so instance
prefixes and the default namespace resolve against the instance
document and unbound prefixes match nothing. Streaming also gains the
tree walk's empty-element rule. The spec suite's instance level is
fully clean: valid 289/289, invalid 291/291; only the asserted
schema-correctness class remains.
DocumentType.validityFindings carries ValidityFinding values (reason
plus subject) instead of strings, DTDSchema.declarationErrors holds
ready ValidationErrors, and every declaration-level finding renders at
its declaration's coding path (x, r/@a) instead of at the document
root, matching the XSD consistency-errors precedent. Texts unchanged.
Each grammar element opens a define scope (scope-mangled names in the
flat table) with parentRef reaching the enclosing scope; includes are
transitive and include-level defines replace the included grammar's
same-name defines (4.7 override); div wrappers flatten while keeping
ns/datatypeLibrary inheritance (4.11); value text stays untrimmed so
whitespace-preserving datatypes compare exactly (6.2.9); dataExcept
recurses through choices. Spec suite: valid 286/289, invalid 287/291;
the six remaining instance cases are all the QName datatype.
The compiler implements simplification 4.9-4.10 (ns inheritance across
ancestors and document boundaries; QName resolution against in-scope
xmlns declarations; the attribute name= shorthand stays namespace-less),
include brings in the included grammar's start with overrides (4.7),
multiple starts and defines combine with a single omitted combine
merging by the named method (4.17), data/except lands as a dataExcept
pattern in the derivative engine (4.12), an empty element matches data
whose lexical space admits the empty string, and whitespace-only
attribute values match empty-matching patterns. Spec suite: valid
274/289, invalid 279/291.
Foreign-namespace elements are stripped before pattern interpretation
(namespace-less elements count only inside fully unqualified schemas),
name/type/combine values are whitespace-trimmed, and include and
externalRef hrefs resolve against in-scope xml:base attributes and the
loaded document's URI, threaded through nested loads with visited
tracking on resolved hrefs. Spec-suite baselines tighten to valid
242/289 and invalid 278/291.
James Clark's spectest.xml runs opt-in via RNG_TS_ROOT: nested
testSuite scopes thread resource/dir definitions into the compiler
loader, and each case asserts schema compile/reject plus per-instance
accept/reject. First measurement carried as exact baselines: all
correct schemas compile, valid 233/289, invalid 277/291; schema
correctness is not yet validated (all 213 incorrect schemas compile,
count asserted). Burn-down classes recorded: grammar-level schema
validation with the 4.16-4.18 restrictions, foreign-namespace
stripping, xml:base-aware resource resolution, and the section 6
compatibility datatypes.
The six worked examples of the C14N 1.0 Recommendation's section 3 run
as input/expected-output tests. They exposed and fixed: top-level
siblings now separated by single line feeds in the canonical form;
superfluous empty default-namespace declarations dropped in inclusive
mode (xmlns="" renders only when undeclaring a rendered non-empty
default); and scalar-level escape loops, so a CR clustered with a
following LF still escapes to 
. Escaping split to its own file
for the length caps.
Closes#132
The reader buffers one Unicode scalar per element, splitting
multi-scalar graphemes from any source, so combining marks cannot merge
with delimiters and the Fifth Edition's scalar-defined name productions
classify correctly; the replacement-text, content-model, and ATTLIST
sub-scanners and the entity-literal validator follow, while grapheme
clusters reassemble wherever scanned text accumulates. Clears the last
eduni baseline, grows the asserted IBM pre-5e class to 300, and with
the xmltest manifest's own EDITION exclusions for 140/141 empties the
xmltest baseline: every xmlconf case applicable to a Fifth Edition,
namespace-aware processor passes.
Closes#135
Limits(strictInternalSubset: true) rejects conditional sections and
parameter-entity references inside markup declarations in the internal
subset, the two feature classes XML 1.0 reserves for the external
subset. DeclSep references and quoted attribute defaults (AttValue)
stay legal; defaults unchanged. The xmltest runner opts in, leaving
case 141 (pre-Fifth-Edition name classes) as its only deviation.
Closes#128
A relative system identifier declared inside an external entity
resolves against that entity's own URI (RFC 3986, the C14N resolver):
ExternalID gains base and resolvedSystemID, the scanner threads the
current entity's URI through external-subset and PE scans, and
resolvers receive the merged identifier. Clears eduni E18; the eduni
baseline now holds only the grapheme-lexing class (#135).
Closes#138
A declared 16/32-bit encoding over BOM-less 8-bit bytes is rejected; a
BOM followed by a declaration outside its family is rejected, reading
the declaration through the BOM's own byte pattern; and an external
entity whose text declaration names a higher XML version than the
document is refused (errata E38). The eduni not-wf baseline is empty.
Reader and decoder helpers split for the length caps.
Closes#137
The namespace layer rejects malformed qualified names, declarations of
the xmlns prefix, misbindings of the xml prefix and either reserved
namespace name (including as the default namespace), and prefix
undeclaration; attributes must be distinct by expanded name; PI targets
and entity/notation names are NCNames; and DTD-typed xmlns values bind
their normalized form. Clears all 18 namespace cases from the eduni
baseline; xmltest valid/sa/012 joins the documented deviations per the
suite's own NAMESPACE='no' flag.
Closes#136
The eduni sections run with exact classified baselines. Fixes: 3.3.3
CDATA attribute-value normalization (literal whitespace to space before
reference decoding; char-ref whitespace survives; tokenized collapse on
SPACE only); production-68 lenient undeclared entities in content and
attribute values (validity finding, reference kept literal, nothing
fetched); errata E15 (references/comments/PIs/whitespace in EMPTY,
char-ref whitespace as data in element content, double-escape shape
included); errata E2 duplicate enumeration tokens; errata E14
declarations completed inside PE replacements (VC: Proper
Declaration/PE Nesting); NCName ID values; namespace declarations
subject to the every-attribute-declared rule. Reader validity machinery
split to EventReaderValidity for caps.
Closes#127
All 13 cases of the xmlconf japanese section decode through the
package byte decoder (UTF-8, UTF-16 both orders, Shift_JIS, EUC-JP,
ISO-2022-JP), parse, and DTD-validate cleanly with zero deviations.
The optional encodings the suite marks TYPE='error' are all supported,
so every case is held to the must-parse bar.
Closes#126
The IBM section (1094 cases) runs clean to two documented classes:
279 pre-Fifth-Edition character-class cases (P85-89, count asserted
exactly) and 2 PE-in-internal-subset feature cases. Real gaps closed:
a document needs a root element (production 1); entity references in
literals must be Names or character references; WFC: No Recursion
checked at declaration over the general/parameter reference graph;
undeclared PE references split into WFC (standalone, or no external
declarations possible) versus deferred validity finding, also for
attribute-default references; refused external PEs are neither; and
groups split across PE replacements report VC: Proper Group/PE
Nesting. Entity machinery split to DoctypeScannerEntities for caps.
Closes#125
The scanner records declaration provenance (internal-subset entities,
element models, attribute lists); the validator reports the three
standalone='yes' dependencies on the external subset: a default that
would be supplied, a non-CDATA normalization that would change a value,
and whitespace in externally-declared element content. The parser hides
externally-declared entities from standalone documents, so referencing
one reports as undeclared (WFC: Entity Declared, 2.9). The Sun section
is fully clean: not-wf 56/56, valid 28/28, invalid 74/74, no baseline.
Closes#134Closes#124
VC Root Element Type (root matches the DOCTYPE name), VC Unique
Element Type Declaration, VC No Duplicate Types in mixed content, VC
One ID per Element Type, VC Notation Attributes and Notation Declared,
VC Attribute Default Legal plus ID Attribute Default, lexical Name
checks for the ID family, and CDATA as character data in element
content. Strict mode adds VC Attribute Value Type (every attribute
declared; namespace declarations exempt). Declaration findings are
computed once at schema build and reported at the document root. Sun
invalid coverage moves from 43/74 to 62/74; the twelve remaining are
all the standalone='yes' family.
A general entity whose replacement text contains markup (directly or
transitively) is reparsed as content at the reference (4.4.2 Included):
the replacement is WFC-validated, cycle-checked, and budgeted, then
pushed back into the reader stream, so its elements become elements in
the tree and the pull-event stream rather than escaped character data.
Character references in internal entity literals now expand at
declaration time for general entities too (4.4.5), making char-ref
markup splice and the Appendix D double escape render as a literal
ampersand; the reference-time WFC validates remaining references
instead of re-expanding. Text-only entities keep the coalescing
single-pass path. Sun valid is 28/28.
Closes#133
Tokenized (non-CDATA) attribute values normalize before validity
checks, so enumerations, NOTATION lists, and the ID/IDREF table see
collapsed values. External parsed entities lose their leading text
declaration (validated: version optional, encoding required, never
standalone) instead of carrying it into replacement text. Character
references in PE literals expand at declaration time, making the
Appendix D '%zz;' example parse. A PI target inside the DTD subset
must be separated from its data. Sun baselines tighten to not-wf 55/56
and valid 26/28; the two remaining valid failures share one cause
(replacement text with markup is included as character data, filed
separately).
The first runner to exercise the validity layer: not-wf must be
rejected (54/56), valid must parse and DTD-validate clean (19/28),
invalid must parse but report at least one validity error (43/74).
Deviation baselines are exact and annotated with their causes, the
burn-down list for #124: tokenized attribute-value normalization,
external-entity text declarations, declaration-time char-ref expansion
in PE literals, standalone VCs, ID/IDREF corners, REQUIRED enforcement,
per-type attribute VCs, and the root/DOCTYPE name match.
The OASIS/NIST section of the W3C conformance suite runs via a new
XMLCONF_ROOT-gated runner driven by the section's own manifest (parsed
with PureXML): 247/247 not-wf rejected, all 100 well-formed cases parse,
zero deviations. Closing its 24 gaps makes the DTD subset grammar
strict: exact PEReference shape, strict declaration names and keywords,
NDATA and notation tails, no bare '%' in entity values, case-sensitive
balanced conditional sections, junk between declarations rejected,
external-subset violations now propagate (with text-declaration
support, production 77), and a PI target must be separated from its
data. The xmltest baseline tightens to 181/186: CDATA in the internal
subset (107) is now rejected, five documented deviations remain.
Closes#123
The derivation final check and Particle Valid (Restriction) move from
fail-fast throws at schema compile into composable Validation rules
(finalRespected, restrictionsAreSubsets) over per-type SchemaTypeFact
subjects, so a schema with several problems reports every finding at
once. SchemaError gains .inconsistent([String]) carrying all findings
(texts unchanged) and drops .finalViolation/.invalidRestriction.
checkRedefine, checkAllGroups, and notASchema stay throws: they examine
the raw schema source, the compilation analog of well-formedness.
Implement the replacement-text constraint at the point of reference: when a
general entity is included, its replacement (character references expanded
as at declaration time) must reparse as balanced content in isolation, via a
new EntityReplacementGrammar mini-parser. This rejects a bare or incomplete
reference ('&', '	' unterminated), tags spanning the entity boundary
('</foo><foo>'), a raw '<' or incomplete reference inside an embedded
attribute value, '<' followed by a non-name character, and a reserved-target
PI in the replacement, exactly the suite's semantics, including that an
UNREFERENCED entity may carry any value and that only the first declaration
of a name binds. Attribute-list defaults must reference already-declared
internal (not external/unparsed/forward-declared) entities with a
non-recursive chain. A CDATA section inside replacement text now shields its
content from reference expansion, fixing the last valid-side case.
W3C xmltest final standing: valid/sa 119/119, not-wf/sa 180/186, with the
six remaining deviations all deliberate and documented in the baseline:
internal-subset conditional/CDATA sections (063, 107) and parameter-entity
references (160-162) are features this package supports, and 141 expects the
1998 suite's name-character classes where this package implements XML 1.0
Fifth Edition's. Zero false positives across all 846 tests at every step.
Closes#120
Make the DTD declaration grammar strict: <!ENTITY> requires its whitespace
(after the keyword, around %, after the name), a real name (not #DEFAULT),
nothing but '>' after the value, NDATA preceded by whitespace and forbidden
on parameter entities; entity-value literals are validated (XML Chars only,
every & a complete reference); SYSTEM/PUBLIC external identifiers parse
strictly (PUBLIC needs both literals for entities and the DOCTYPE, public-only
stays legal for notations) with PubidChar validation; <!ATTLIST> bodies are
validated against XML 1.0 productions 52-60 via a new DTDAttListGrammar
(spacing, attribute types, enumerations, quoted defaults); the reserved xml
PI target is rejected inside the subset. Also: strict UTF-8 decoding (no
silent replacement of malformed sequences), XML Char checks in attribute
values and CDATA, the declaration's version/encoding value grammar, and
required whitespace between pseudo-attributes. The strict machinery lives in
DoctypeScannerStrict/DTDAttListGrammar to stay under the length caps.
W3C xmltest: not-wf/sa 162/186 rejected (from 129; 80 at first contact),
valid/sa 118/119, zero false positives across all 846 tests at every step.
The remaining 24-case baseline is exactly: the entity replacement-text class
(19) and the deliberate internal-subset extensions this package supports as
features (conditional sections, PEs in the internal subset: 5).
Part of #120, #105
Third W3C-suite strictness pass: DTDContentModelGrammar validates each
element declaration's content specification against the XML 1.0 grammar
(productions 46-51) at DTD scan time, EMPTY/ANY, Mixed (with #PCDATA first,
names only, the trailing * required with alternatives, no nesting), and
children (one connector per group, quantifiers bound directly to their
particle, balanced parentheses, no empty groups, no SGML leftovers like
'- -', 'O O', '&' connectors, or inclusion/exclusion suffixes). The element
declaration also requires whitespace after <!ELEMENT and after the name. The
lenient ContentModelParser still drives validation behavior; this is a
well-formedness gate. not-wf/sa: 129/186 rejected (from 109); valid/sa
unchanged; zero false positives across all 846 suite tests; baseline rebased
to the exact 57 remaining (declaration-grammar details and the entity
replacement-text class).
Part of #120, #105
Character references now require lowercase 'x' for hex and a referenced code
point inside the XML Char production (rejecting �, , ,
surrogates, and X). The reserved 'xml' processing-instruction target
(any case) is legal only as the declaration at the document's very first
bytes: whitespace or a comment before <?xml ...?>, a declaration inside
content or after the root, and case variants like <?XML?> are all rejected.
Comments and PI data are checked for the XML Char production like content.
not-wf/sa: 109/186 rejected (from 93); valid/sa unchanged at 118/119; all
846 suite tests green, baseline rebased to the exact 77 remaining (the
internal-subset grammar and entity replacement-text classes on #120).
Part of #120, #105
Add five well-formedness checks the W3C xmltest suite surfaced: '--' inside
comments (also rejecting the ---> ending), raw '<' in attribute values, the
literal ]]> sequence in character data, attributes not separated by
whitespace, and characters outside the XML Char production in content, each
a located ParseError. The attribute scanners move to EventReaderAttributes
to stay under the type-body cap.
Add the opt-in W3C xmltest runner (XMLTS_ROOT-gated; the suite is never
vendored, James Clark's license permits redistribution only as the unmodified
archive; Foundation is used in this one test file for file access only).
Baseline: valid/sa 118/119, not-wf/sa 93/186 rejected (up from 80), the
remaining 93 carried as an exact known-deviations baseline so progress and
regressions are both visible. The two remaining leniency classes (internal-
subset DTD grammar, entity replacement-text well-formedness) are #120.
Part of #105 (Tier 2)
Grow the Tier-2 conformance corpus with 7 OASIS catalog cases through the
harness: exact system/public/uri entries, rewriteSystem and rewriteURI prefix
matching, and the unresolved outcomes for unmatched identifiers. All conform.
Part of #105 (Tier 2)
Grow the Tier-2 conformance corpus with 17 XSD regex cases through the
pattern-facet path: implicit whole-string anchoring, the character-class
escapes (backslash-d/w/s), Unicode category and negated-category escapes,
quantifier ranges (exact, bounded, open), alternation, grouping, negated
character classes, and class subtraction. All conform.
Part of #105 (Tier 2)
Grow the Tier-2 conformance corpus with 10 cases through the harness:
XInclude substitution, parse=text inclusion with escaping, xi:fallback on a
missing href, and relative href resolution against the base; XPointer
shorthand ids, element() navigation from an id and from the root, and
xpointer() including the classic per-step predicate semantic (//para[1]
selects every parent-first para; (//para)[1] the document-first), which the
corpus now locks explicitly.
Part of #105 (Tier 2)
A complex type derived by restriction is checked at schema compile to accept
a structural subset of its base, closing the declared XSD 1.0 spec gap.
ParticleRestriction covers element name matching, element-vs-wildcard
admission, wildcard narrowing, occurrence-range subsumption, and the group
recursions: sequence/all order-preserving with emptiable skips (Recurse),
choice mapping (RecurseLax), sequence-into-choice (MapAndSum, approximated by
per-particle checks, a documented simplification), sequence-into-all
(RecurseUnordered), and RecurseAsIfGroup for a lone element against a group.
An unfaithful restriction throws SchemaError.invalidRestriction(type:base:
reason:). All 834 pre-existing tests pass unchanged (no false positives on
the existing restriction-using schemas); 7 new tests cover the accept and
reject paths plus a conformance-harness pair.
Closes#117
Extract PathKey.steps(forChildNames:) as the single path construction behind
the validator walk, the XSD content validator, and the identity validator,
replacing three identical implementations, so located errors can never
disagree on a path. Add two differentials locking the duplicated engines
together: equivalent DTD and XSD content models (sequence, choice, *, +, ?,
nested choice) must agree on every child sequence across the positional
matcher and the Thompson NFA; and the pull (EventReader) and push
(PushScanner) tokenizers must yield the same event stream for the same
document, even with the push side fed one character at a time (adjacent text
events coalesced, since chunk boundaries legitimately split text). Both
pairs agree on everything today; the differentials guard them.
Closes#115
Deepen the two thin coverage zones (#119) through the validation-driven
harness. Serializer options matrix (10 cases): self-close on/off, CDATA kept
vs as-text, asciiOnly hex character references, round-trip carriage-return
escaping, declaration with standalone, exact pretty-print shape, attribute
escapes, and the Latin-1 output-encoding declaration via the byte path. HTML
depth (8 cases): the adoption agency's furthest-block and deep-misnesting
paths, foster-parented table text (with the implied tbody per the HTML5
algorithm), template content nesting through the document parser, and
raw-text script, implied dt/dd and table-cell closes, and comments through
the fragment parser. All conform; the one initial mismatch was a wrong
expectation in the test (the implied tbody), not a code divergence.
Closes#119
Lock the strict and recovering parse paths together: recovery synthesizes
events through machinery the strict path never exercises, so a 21-document
corpus of well-formed input (the C14N conformance inputs plus nesting,
mixed content, attribute quoting/escapes, namespaces and redeclaration,
entities, character references, prolog, comments, CDATA, xml:space) asserts
that PureXML.read produces the identical Node tree as PureXML.parse with no
diagnostics, and that readTree's editor tree projects to the same node. Both
paths agree on every document; the differential now guards them.
Closes#116
Document the weak-parent ownership trap at the public entry points: parseTree
and readTree now state that a tree (or ownerDocument) must be held while using
any node inside it, that TreeNode has no internal synchronization (confine to
one thread or actor), and that the immutable Sendable Node projection is the
way across concurrency boundaries; the TreeNode class doc carries the same
contract. QualifiedName's malformed-colon fallback (':local', 'prefix:', '::'
stay whole and unprefixed), already implemented, is now documented on init
and locked by a test.
Closes#114
A selector or field XPath that fails to compile is now reported once up
front as a located error (identity constraint 'k': invalid selector/field
XPath '...'), instead of try? silently turning a schema author's typo into
a disabled constraint. The per-run query cache from #112 is the choke point:
compileErrors() probes every constraint's selector and fields in
deterministic order, the failures cache as nil, and the walk afterwards
treats those constraints as matching nothing, so the rest of the document
still validates. Tests cover a malformed field and a malformed selector.
Closes#111
XSLT: template selection resolves each match pattern once per transform via
a per-run MatchCache (the pattern's node set is computed once over the source
tree; selection becomes an identity lookup), replacing per-(node, template)
recompilation and full-tree re-walks. XSD identity validation: a per-run query
cache compiles each selector/field XPath once instead of at every visited
element. Schematron was verified to already store compiled queries. Behavior
unchanged (all suites green); a multi-template shape test over 300 nodes
guards the optimized path. MatchCache lives in its own file to keep the
transformer under the length cap.
Closes#112
An xsi:type naming an undeclared type is now a located error in both the
tree validator (validateChild) and the streaming driver, instead of a silent
fallback to the declared type. typeReference chains resolve through one
shared resolver (resolveReference, with a visited set), replacing the inline
recursion, the 64-hop cap, and the completions guard: a circular chain now
reports 'circular type reference' instead of silently truncating, and the
streaming shallow check no longer recurses without bound on a cyclic table
(a latent crash). Tests cover unknown xsi:type (tree + streaming agree),
the circular chain (tree + shallow), the resolver's three outcomes, and a
conformance-harness case pair.
Closes#110
Grow the Tier-2 conformance corpus with 14 DTD content-model cases (sequence
order/completeness, choice exclusivity, the *, +, ? occurrence indicators,
#PCDATA, mixed content, EMPTY, and ANY) validated against the internal subset
and checked through the validation-driven harness. Own suite.
Part of #105 (Tier 2)
Grow the Tier-2 conformance corpus with 13 XPath navigation cases (descendant
and all-element counts, positional and last() predicates, ancestor and
ancestor-or-self axes, following/preceding-sibling, the attribute axis, an
attribute predicate, union, the parent abbreviation, and position()) over a
fixed tree, checked through the validation-driven harness. Own suite.
Part of #105 (Tier 2)
Grow the Tier-2 conformance corpus with 4 Canonical XML mode cases: exclusive
drops an unused namespace and renders one at its point of use; Canonical XML
2.0 drops whitespace-only text nodes and trims surrounding whitespace. Its own
suite (ConformanceCanonicalModesTests).
Part of #105 (Tier 2)
Grow the Tier-2 conformance corpus with 7 Schematron cases (assert satisfied/
violated, an inert non-matching context, numeric comparison, and report fired/
not-fired) checked through the validation-driven harness. Moved to its own
suite (ConformanceSchematronTests) so the main corpus stays under the
type-body cap.
Part of #105 (Tier 2)
Rule-canon audit (validation-rules.md / the OpenAPIKit idiom): the streaming
XSD validator was the one surface applying a bare method (validateShallow)
rather than a Validation<> value. Wrap it: ComplexValidator.shallowValidity is
a Validation<ResolvedElement, ComplexValidator> whose subject carries the
element with its already-resolved effective type (the contextual typing a
node-tree walk cannot express), and the streaming driver applies it via
apply(to:at:in:). Now every validation surface, DTD, XSD, RELAX NG, Schematron,
HTML, structural, conformance, and both streaming validators, routes through a
Validation value. Adds a direct unit test of the rule.
The fragment TreeBuilder gains the HTML5 active-formatting-list and reconstruct
step that the document builder already had: when a formatting element (b, i,
em, ...) is closed out of order, it is remembered and re-opened for the
following content. So HTML.parse now agrees with HTML.parseDocument and the
spec, e.g. <b><i></b>X</i> -> <b><i></i></b><i>X</i> and
<p>1<b>2<i>3</b>4</i>5</p> -> <p>1<b>2<i>3</i></b><i>4</i>5</p>. The conformance
corpus that surfaced this now checks the fragment path directly.
Closes#109
Grow the Tier-2 conformance corpus with 8 HTML5 cases (void elements, implied
li/p closing, tag-case normalization, the adoption agency with and without
trailing text, entity decoding, stray-end-tag) checked through the
validation-driven harness against the HTML5 parsing algorithm.
The corpus surfaced its first real divergence: HTML.parse (fragment) does not
reconstruct active formatting elements the way HTML.parseDocument (document,
spec-correct) does, so <b><i></b>X</i> yields <b><i></i></b>X instead of
<b><i></i></b><i>X</i>. The corpus uses the document path (spec-correct) and
the divergence is filed as #109.
Grow the Tier-2 conformance corpus with 10 XSLT cases (value-of, for-each,

checked through the validation-driven harness against the spec output.
Part of #105 (Tier 2)
Grow the Tier-2 conformance corpus with 12 RELAX NG pattern cases (text,
optional, oneOrMore, choice, ordered group, required attribute, interleave,
empty) validated through the public compact-syntax API and checked through
the validation-driven harness against the pattern semantics.
Part of #105 (Tier 2)
Grow the Tier-2 conformance corpus with 13 XSD datatype and facet cases

their spec-mandated string results.
