Mihaela Mihaljevic 45f2e7dbf5 fix(schema): an untyped substitutionGroup member inherits its head's type ... XSD 1.0 3.3.2: an element with neither a `type` attribute nor an inline type, but a `substitutionGroup`, takes the {type definition} of its head. PureXML defaulted such an element to `anyType`, so an instance of it accepted any content. `XSDParser.elementType` now resolves the head declaration through `context.globalElements` (transitively, with a cycle guard) and uses its type. XSTS invalid-instances-accepted 29 -> 28 (typeDef00204m: <root>Yes</root> is no longer accepted where root substitutes a boolean head), no other bucket moved (valid-schemas-rejected and valid-instances-rejected held at 0 across all 14383 groups). 1451 unit tests pass.		2026-06-20 02:47:07 +02:00
