  '''Status of assertions development:''' The assertions traverser (the Xerces 
component responsible for recognizing xs:assert and xs:assertion syntax in XML 
Schema instances, as defined in the XML Schema specification) support both for 
Simple and Complex type definitions is complete, and Xerces team has checked in 
the code for this, at the SVN repository 
(https://svn.apache.org/repos/asf/xerces/java/branches/xml-schema-1.1-dev/).
- The development of XPath 2.0 processing for assertions is underway. A major 
XPath 2.0 integration algorithm is complete and tested with Xerces Schema 
validator. We are working further to enhance it.
+ The development of XPath 2.0 processing for assertions is nearly complete. We 
are working further to enhance the XPath 2.0 support. At this point, most major 
assertions XPath 2.0 scenarios can be written by the users, and are usable with 
Xerces-J. Xerces team is currently reviewing the XPath 2.0 code for assertions, 
and we could see it available in the SVN repository in near future.

- We are designing a Java interface API for integrating Xerces with an XPath 
2.0 engine. It should be possible to plug in any compliant XPath 2.0 engine to 
the Xerces assertions processor; by writing a small interface layer (a Java 
class, or a set of classes) complying to this interface.
