Thanks Gary,
Sorry to make you look into an already fixed problem. I looked for a bug
report before reporting this but didn't find one. I'll try it out with
2.2.D06.

Dave --
This is working in the most recent released and was definitely a bug in
XalanJ 2.1.0 and earlier but has since been fixed. You might try your
stuff with XalanJ 2.2.D06 and verify that it works before we do the real
2.2.0 release.
