It would seem that many people are mad that XHTML 2.0 may be 
non-backwards compatible with previous versions. IMHO, you have to draw 
the line somewhere. If we keep supporting old semantics, we will never 
be able to use new semantics.

This reminds me of times when OS upgrades promise a new, revolutionary 
feature that is removed by GM because users of older versions complain 
it will make their workflow incompatible. But IMHO it would be better 
to adapt to the new system so that newcomers to the language find it 
better semantically. (See 'Mac OS X'.)

The W3C has the potential to break some nasty habits semantically in 
(X)HTML with the current situation in XHTML 2.0. Don't lose some of 
these new features to older semantics.
