[PR] resolve QName field values against the instance in IdentityConstraint [poi-xmlbeans]
aizu-m opened a new pull request, #141:
URL: https://github.com/apache/poi-xmlbeans/pull/141
Validating against a schema whose `xs:unique`/`xs:keyref` field is an `xs:QName`, with `xmlns:p='urn:p'` on the root:
<t:k n='p:a'/><t:k n='p:a'/> xs:unique validate(): true (expected cvc-identity-constraint.4.1)
<t:k n='p:a'/><t:ref n='p:zzz'/> xs:keyref validate(): true (expected cvc-identity-constraint.4.3)
<t:k n='p:a'/><t:ref n='p:a'/> xs:key error: Key kk@urn:t is missing field with xpath: '@n'
Found while auditing the validator for constraint checks that an instance can slip past. Unprefixed QNames behave. Prefixed ones do not.
`IdentityConstraint.FieldState.attr` and `FieldState.text` build each field value with `st.newValue(value)`. No `NamespaceContext` is pushed, so the prefix cannot be resolved. `newValue` throws, the helper swallows it and returns null, and the field is treated as unfilled. The value never enters the node table. Duplicates and dangling keyrefs go unreported, and a valid document using `xs:key` is rejected.
The `Event` passed in is already a `PrefixResolver`. `Validator` pushes `new NamespaceContext(event)` before `newValue` for union enumerations. This does the same at the two field-value sites. The ID/IDREF paths are unchanged.
Same result through `ValidatingXMLStreamReader`. Added `QNameIdentityConstraintValidateTest`. All three cases fail before the change and pass after. `./gradlew test` passes.
