Mukul Gandhi updated XERCESJ-1541:
----------------------------------
Description:
I thought it's good to create this JIRA issue for tracking purposes.
Following is a summary of significant enhancements we've done to XSD 1.1 CTA
implementation within Xerces, post 2.11.0 release.
- added in-scope namespaces to XDM tree for type alternatives (for full XPath
mode evaluation). this makes possible namespace aware operations on CTA XDM
nodes (e.g fn:resolve-QName etc).
- enhanced static type checking of CTA XPath expressions. essentially to raise
certain errors during static analysis phase for XPath expressions (after
parsing and before evaluation), for e.g to detect of the schema type used in
XPath expression is not present in in-scope schema types in XPath static
context, or if the namespace prefix used in XPath expressions is declared.
- the XDM tree of CTA now carry the document URI of the parent document.
- we now set base-uri property in CTA's XPath static context.
- we now correctly set type annotations on CTA XDM nodes, namely xs:untyped on
the root element node, and xs:untypedAtomic on it's possible attributes.
Other than these, we've made improvements to quite a few XPath 2.0 F&O
implementations within PsychoPath XPath engine, which will benefit both CTA and
assertions.
