> I thought it's good to create a JIRA issue for these changes for tracking
> purposes. We made following enhancements to the XSD 1.1 CTA implementation
> post 2.11.0 release.
> 1. The in-scope namespaces are now visible within XDM trees for CTA, when
> working in full XPath 2.0 mode. This makes possible namespace aware
> operations on CTA XDM nodes (e.g fn:resolve-QName etc).
> 2. There's now an enhanced static type checking of CTA XPath expressions.
> This is essentially to raise certain errors during static analysis phase for
> XPath evaluations (for e.g to detect if the schema type used in XPath
> expression is present in in-scope schema types, or if the namespace prefix
> used in XPath expressions is declared).
> 3. The XDM tree of CTA now carry the document URI of the parent document.
> 4. We now set base-uri property in CTA's XPath static context.
> 5. We now correctly set type annotations on CTA XDM nodes, namely the type
> xs:untyped on the CTA root node (which would be an element node), and
> xs:untypedAtomic on it's possible attributes.
> 6. Providing an improved PsychoPath XPath 2.0 JAR file. This includes quite a
> few improvements to couple of XPath 2.0 F&O function implementations, and few
> other enhancements. This provides benefits for CTA (when working in full
> XPath 2.0 mode) and <assert> processing.
> 7. CTA fixes mentioned in JIRA issues XERCESJ-1533, XERCESJ-1508,
> XERCESJ-1503.
