Re: grouping-size

Hi Michael:

Thanks for your insight. That all makes sense.

I knew that XSL-FO 2.0 was stalled, but didn't realize it was dead. If
there is interest in reviving it, I would be interested in helping. I have
worked on two open-source Java implementations, and continue to work on one
of those now. I have doubts about how useful that experience would be in
helping to move a standard forward.
