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.
