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
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).
