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
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
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
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.
