Bug #2962

Lax validation doesn't use the XML namespace schema
Category:
Schema-Aware processing
Fix Committed on Branch:
trunk
Fixed in Maintenance Release:
Description
When lax validation is initiated, typically from XSLT or XQuery code, the schema for the XML namespace is used only if it has been explicitly imported. This means that xml:id attributes will not be validated as unique unless the XML namespace is imported. Since Saxon has built-in knowledge of the XML namespace it should probably be implicitly imported.

- Fix Committed on Branch 9.7, 9.8 added
Added a call to addSchemaForXmlNamespace() to the initializer for EnterpriseConfiguration.
Tested by a QT3 test for fn:idref() generated from the examples in the F+O spec.

Bug fix applied in the Saxon 9.7.0.10 maintenance release
- Status changed from Closed to In Progress
Unfortunately the fix for this issue (included in 9.7.0.10) has a nasty side-effect - creating an EnterpriseConfiguration fails if there is no license file on the classpath. This prevents other methods of supplying a license file working, and prevents fallback to unlicensed mode.
Another side-effect has been reported: SCM files that include declarations of attributes in the XML namespace will no longer load, because they are treated as duplicates.
If I remove the code that adds the XML-namespace schema, the following QT3 tests fail
-s:app-spec-examples -t:fo-test-fn-idref-001

I think these two test cases make the assumption that the schema for the XML namespace is implicitly imported, and there is nothing in the spec to justify this assumption. We should change the test cases to explicitly import this namespace (not trivial since they are auto-generated from examples in the spec.)

9.7)
I have changed config.getElementDecl() and config.getAttributeDecl() on the 9.8 branch so that when (a) the requested declaration does not exist, and (b) the target namespace is one of those for which a built-in schema is available (XML, FN, XSI), then the built-in schema is instantiated and the request is repeated. The effect of this is that lax validation of elements and attributes with names such as xml:space or fn:analyze-string-result now performs validation rather than causing it to be skipped.
Having been bitten by the side-effects of the previous attempt at solving this, I'm going to make this solution apply to 9.8 only.
