I assume that *after* it has parsed the HTML there is something isomorphic
to a DOM inside and this must have properly nested elements. [I appreciate
that really bad HTML may give erroneous results, but that is not our
problem.]. It should then be possible to extract this as xHTML and:
(a) mix it with other XML
(b) render it in the Swing Component

The other thing I'd like to do is generate HTML as a string (e.g
String s = "<P><EM>Hello</EM> world</P>";
and pass s to the renderer. Any idea how?

This would then give us part of an XML2HTML renderer in Swing

BTW I am making progress with JUMBO2beta. I have had a moderate amount of
feedback, all of which was very useful. I am really keen that we use Swing
to enhance our functionality here. Also, someone told me yesterday that the
next versions of Swing were promised to be much faster and better...RSN
