Hi Gary,
Thanks for volunteering your help.
Here is a stack trace and the responsible XSL file.
I'm using Xalan-J 2.3.1, just the regular Xalan-J (not XSLTC). I'm
running from the command line with the 'java' command on Windows 2000
Server.
I don't know the rules for posting attachments to the list; if it is
acceptable, do you think you could forward this message to the list?
Thanks,
Toby
