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.
Convert the four simple-type-pass compile checkers to located findings so
each error attaches to its own declaring node instead of the schema root
(#169): a list whose item type is itself a list or a union containing a
list and a list declaring both or neither of itemType/inline simpleType
(simpleTypeVarietyFindings), an empty union, a simpleType restriction whose
base resolves to a complex type (simpleTypeBaseNotComplexFindings), an
itemType/memberType referencing a type final for list/union derivation
(simpleTypeFinalFindings), and an attribute typed by a complex type
(attributeTypeMustBeSimpleFindings).
Each predicate, traversal order, and reason string is unchanged; only the
location each finding carries differs, from the schema root to the
offending list, union, restriction, or attribute node. The four checkers
had exactly one caller each (their compile-rule dispatch), so each is
renamed in place and the .unlocated wrap dropped, leaving no dead wrapper.
Adds a located-diagnostics test per checker in a new suite kept within the
type-body budget.
A list simple type must draw its item type from exactly one of an itemType
attribute or an inline simpleType child; neither, or both, is invalid. A union
must declare at least one member type through a memberTypes attribute or an
inline simpleType child; an empty union declares none (src-simple-type.2/.3).
XSTS invalid-schemas-accepted 215 to 214, no other bucket moved.
