One of the things that I see as a potential problem is that HTML etc as it
is used now has 2 (as I count them this side of the morning) relatively
distinct uses.
	1) as an alternate form of (relatively) static information.
	2) as a (very-basic) cross-platform (g)ui.

XSL and DSSSL are focusing rather hard on (1), but not on (2).  That may
not be a bad thing if it is made clear that from the designers point of
view (2) is better left to java, which it would be if the borwser people
could better integrate java into their browsers.  the problem is that (2)
often spends a lot of time trying to do a lot of the stuff that the display
engine for (1) already has figured out.

hmm... so maybe what I am looking for is a "standard" way to extend a XSL
processing/display engine with new flow-object types at run-time.  Paul,
was it you who talked about this some months ago?  Someone did, so it isn't
a new idea.
