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. ........... Ken -- G.
