Defining extension function that returns a list of objects (regexp groups)

[Karr, David]

I may be jumping the gun on this, but I'm trying to figure out how I can
write a Java extension function that returns a list of objects (list of
strings, being regexp group values), and how to process that list in a
stylesheet.  I don't see exactly how to do this from the Xalan
documentation.

I'm investigating this because I think I can't use the EXSLT
regexp:match function in WebLogic running JDK 1.4.2 (the EXSLT docs seem
to say this, and it fails when I run it in Stylus Studio).
