XHTML is the modern version of HTML -- it went like this:

...

HTML 3.2

HTML 4.0

XHTML 1.0 (three types of DTD)

XHTML 1.1

XHTML 2.0 (coming soon)

XHTML 1.1 is a wonderful simplification of HTML, which gets rid of a lot

of bad old tags, enforces lower-case tags, and insists on all tags being

closed. It also actually functions as well-formed XML, so you can have

an XML document (and work on it through XML DOM parsers, SAX parsers,

XSL Transformations etc.), but it still displays nicely in a browser.

It's a tremendous improvement over the old HTML 4, and most developers

have adopted it wherever possible. There's a brief intro here:

http://www.w3schools.com/xhtml/

I haven't started working with TRichView myself yet, because I want to

make sure it'll do what I need before I start.

Cheers,

Martin
