A nice way to dynamically update HTML on a page (without leaving the
page) is to use document.innerHTML and XMLHTTP in JavaScript, then
communicate with the server via XML snippets (plus some server side
scripts of course, I use PHP5+MySQL). If you want to see an example,
you can take a look at my chat:

(And I was inspired by Google Suggest, which uses XMLHTTP.)

Of course, this can also be used for form validation and similar tasks.

Yes, the notion of text/html as SGML is bogus as well. However, HTML
4.01 provides useful features over the early honest tag soup, and the
soupness of text/html is less likely to contaminate SGML than XML.
Again, for me the choice between XHTML and HTML is an arbitrary one. As
I said I prefer the style of always-closed p's, always-quoted
attributes, always using both attribute-name and attribute-value, and
having the same syntax as XML.
text/html user agents don't enforce your code style preference even if
you pretend to use XHTML. You need external tools for that enforcement.
You can enforce a similar code style with HTML using external tools.
(Try the "fussy mode" of PageValet--no custom DTD required.)
I think it's
equally silly to say "avoid XHTML because there are problems". There
are *always* problems no matter what language you choose on the web.

As far as I can tell, the problems of XHTML served as text/html are a
proper superset of the problems of HTML 4.01 served as text/html. In
general, one is willing to take new problems only in exchange for some
