This is excellent news. I think I can do most of what I need to do

already, and I just need the XHTML output. For the moment, I can start

work with the control to learn what I need to learn, and perhaps

implement my own conversion between HTML and XHTML until the

implementation is ready.

Many thanks for taking the time to explain!

Cheers,

Martin
