It should have been included in the classpath built internally by the 
Barracuda build so putting xmlc in ANT_HOME/lib is not needed.  The only 
reason why xerces would need to go in ANT_HOME/lib is to provide xml 
parsing libraries for Ant itself when running under jdk1.3.x or some other 
JDK which doesn't include JAXP.  Since having xerces2 there will break the 
Barracuda build, they need to be removed and have to be replaced by 
something...which would be the xerces version that comes with 
Barracuda.  Under j2sdk1.4.x, the JAXP parser is automatically available so 
xerces can be removed from ANT_HOME/lib entirely.  And, it the most recent 
CVS, Barracuda's xerces version is included in the internally built 
classpath so everything should work fine with nothing extra in ANT_HOME/lib 
other than JUnit if you want to run the JUnit tests.  That has to do with 
the fact that the JUnit taskdef exists in the parent classloader 
(optional.jar) and can't load JUnit from the child classloader.  The only 
other workaround would be to include optional.jar in Barracuda's internally 
built classpath, but I don't like that idea much and haven't even tested it 
to see if it would work.

I still think it has to be a problem with existing dom packages somewhere 
in the classpath.  JAVA_HOME/jre/ext directory is a place to check.  That 
causes all sorts of issues.
