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 whole-buffer ISO-2022-JP, GB18030, and EUC-TW decoders index the input
ArraySlice directly instead of materializing an Array first (one avoidable
O(n) allocation per decode each); declaredEncoding's subsequence scan uses
elementsEqual instead of allocating an Array per candidate offset. Document
the two analysis-flagged bounds: entity expansion is doubly bounded (the
character budget caps output; the visiting set caps recursion depth at the
number of declared entities), and the RELAX NG derivative engine carries no
memoization by design (the simplifying constructors keep real grammars
small; adversarial nested-choice grammars can grow the residual, so treat
untrusted schemas accordingly). Behavior unchanged, all suites green.
Closes#118
Extend the GBK two-byte subset to full GB18030: a lead byte followed by
a digit opens a four-byte form whose pointer is mapped through the WHATWG
index-gb18030-ranges linear ranges, reaching the supplementary planes.
The 207 ranges are vendored verbatim. Wired into the whole-buffer and
streaming decoders and the encoding-name table (gb18030/gb-18030).
Closes#102
