David,
Thank you for pointing me in the write direction (I strongly suspected I
was missing something). However, one thing, I can't seem to find
documented anywhere how to get the CVS updates. All I can find is how
to download the latest full releases. Also, is there any documentation
of the innards of the Xalan parser anywhere? The only thing I see in
the docs are about the SAX and DOM interfaces.
