> I am providing a patch for XML Schema 1.1 assertions support, for Complex
> Types. Earlier I had submitted an assertions patch for Simple Types, which is
> now available in SVN repository.
> Now the assertions traversal support both for Simple Types and Complex Types
> is complete, except the XPath 2.0 processing.
> Kindly note ...
> 1. The grammar changes, for assertions are now considered (as also discussed
> with Khaled). The details of the XML Schema 1.1 grammar where asserts are
> used is available on the wiki page at,
> http://wiki.apache.org/xerces/XML_Schema_1.1_Assertions.
> 2. A separate traversal class for assertions is not designed, to implement
> assertions for Complex types. Instead, traversal support for assertions is
> added to, XSDComplexTypeTraverser.java. This is done because assertions are
> available in Simple types, as well as Complex types. For simple types,
> assertions are now facets, which required modifying the Facet data structures.
> Due to this, I felt it was appropriate to add traversal method for
> assertions, in XSDComplexTypeTraverser.java instead of having a separate
> traversal class.
> 3. Some error messages, as specified in Xerces properties file need to be
> changed,
> to reflect the new XML Schema 1.1 grammar. This is presently not done.
> 4. XPath 2.0 support for assertions is presently not implemented.
> 5. A test case XML and XSD files is also provided with this patch.
