	Well, due to the inability of one of the other groups here to
just give me data (don't ask, it's a long, sordid story) I have to parse
the data I want out of the SGMl feed they send to our customers. What I
was trying to do was tap into nsgmls and piggy back off of their event
detection to write out the data I need.

	Oh, data relationships, not anything implicit to the SGML
itself.

	Contents.

  <nice example code elided>

	Trying to extract data, keep the data relationships together
(which is meta-knowledge, based on my understanding of the documents,
although it is reflected in the DTD and document instances.)

	It has been helpful - gives me an idea or two that I hadn't
considered. My C++ experience has been mostly classroom (where it all
made sense) and not much Real Life followup because C++ isn't in great
use here and I've been discouraged from using it extensively because
there'd be no one to take over my code if I change jobs/positions :)

	Thanks again for the extensive reply - this has always been a
good forum to ask slightly off-the-wall/topic questions of and get
thoughtful replies.
