The two monolithic XSD content/identity rules only satisfied the OpenAPIKit
validation idiom at the wrong granularity: no per-constraint removability,
no isolable failing/near-miss tests. Split them into 32 named rules, each
finding tagged at its origin and cached per XSDContext so the walk still
runs once per document (the #101 decision against duplicating XSD's
recursive type resolution still holds). Wired the streaming path's ID/IDREF
and identity checks through the same framework instead of calling the
validators imperatively, and added the unwrapAndLookup combinator the rule
already named as required.
Also includes the mandated repo-wide swiftformat/swiftlint pass.
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
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).
