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
The streaming decoder previously selected an encoding only from a byte-order
mark or the UTF sniff, so its single-byte and CJK decode paths were latent. It
now reads the encoding from the XML declaration (the libxml2 behavior) when
there is no BOM, activating those paths over an incremental byte source. Add
the streaming form of ISO-2022-JP, carrying the stateful mode across reads
(extracted to its own file to stay under the type-body cap). A test asserts
streaming agrees with whole-buffer decode for a single-byte (ISO-8859-1), a
CJK (Shift_JIS), and an ISO-2022-JP document.
Part of #108, #105
Add the WHATWG iso-2022-jp decoder, the first stateful encoding: escape
sequences switch between ASCII, JIS X 0201 Roman (yen, overline), JIS X 0201
katakana, and the JIS X 0208 plane, resolved through the shared jis0208 table
(no new data). Tested across all four modes, with the JIS X 0208 kanji
cross-checked against the EUC-JP decoder (same table, same pointer). EUC-TW and
the streaming form of ISO-2022-JP remain.
