Since nobody answered, probably nobody here knows.  I ported Jim
Bender's sxml-match to Chicken, but I didn't end up using it very much
and am hardly an expert in how it works.  You might want to ask Jim
Bender, or the WebIt! mailing list.  It could also be a bug in the
Chicken port, or in some underlying Chicken procedure, although I did
make sure that it passed all of Bender's tests, and the changes I made
were so slight that I don't think they should matter.  But checking
against the canonical PLT version may be a good idea.

Bender's sxml-match page is here:
