Thank you, Sean!

There were some very bored grey cells of mine that got excited when I
started looking at DSSSL/XSL, and I now think they must have been the
RPG-II ones that have been quiescent for 2 decades.

In some ways you are correct ... the implicit traversal of the RPG-II
program (vs. document instance), triggering on flags (vs. construction
rules), is quite similar.

I've been wondering what nagging recollection of programming heritage was
being tickled by this work, and I think you've nailed it.
