Right, so the spec contains sample code that is made invalid by an errata  
:-(

I've got Ant 1.7.0, I'm not entirely sure where to find other relevant  
version information but there is a file called libraries.properties where  
these entries look relevant:

xerces.version=2.8.1
xercesImpl.version=${xerces.version}
#should be in sync w/ xerces, but not in the maven repository
#xmlParserAPIs.version=${xerces.version}
xmlParserAPIs.version=2.6.1
xalan.version=2.7.0
xml-resolver.version=1.1

Is that what you need?
