Awesome . . . that works perfectly, and is actually pretty fast (1:12 to
process 204 files, comprising over 2200 table rows, on Saxon/Win2K).  Thanks
again.  I'm not sure I understand yet how you use generate-id in this
approach, but I think I'll figure it out from looking through the FAQ again.

(Now I get to do this again for U.S. airports--their stylesheets are
formatted differently, and I have to generate a "state-province" node, plus
make a distinction between commercial/non-commercial airports, which will
introduce even more grouping issues--but I think I can take it from here.)

thanks,
b.
