Wordpress uses XML-*like* syntax, but uses string concatenation and
serves the whole thing as text/html (so no browser even try to use its
XML parser; all browsers out there use their HTML/tag-soup parser).
Moreover, it's really easy to change Wordpress's template to output
HTML5 (though Wordpress has some hard-coded "/>" in it; if Wordpress
wordked with a DOM, it'd only be a matter of serialization).

There are really few people really doing XHTML (i.e. serving it as
application/xhtml+xml). Most people pretending they do XHTML (i.e.
serve XML-like documents as text/html) are failing to do it right
(someone sent some figures to this list or the WHATWG a few
weeks/months ago).

I don't expect XHTML5 to live on the Web.
XHTML is a wonderful thing when mixing HTML with other XML
vocabularies and/or using an XML toolchain (and even then, you could
just use an HTML parser and then work with the DOM); but I do think
that XHTML on the Web has failed.

First, HTML5 has been designed to be backwards compatible (at least
wrt parsing, if not at the validation stage) so that most valid HTML 4
(or previous versions) documents will still be valid HTML5 documents.
Second, if you're doing HTML 4 correctly, why would you bother moving
to HTML5? (provided you have no need of HTML5 additions)

Many pages on the wild are still HTML 3.2, most pages still use
<!--comments--> around their inlined <style> and <script>, etc. Most
people have made no change to their pages for ages, so why would they
suddenly switch to HTML5?

New products (or new versions of existing products) will probably
align on HTML5, but so what? Many people are still using IE 6, some
are still using Firefox 1.5, why would they switch to an
HTML5-compliant browser? and such a browser would still have to be
"compatible" with non-HTML5 pages, so why switch to produce HTML5
pages? (provided you have no need of HTML5 additions)

You said that adding the xmlns declaration would be done automatically
when converting to XHTML; Anne replied that html5lib (among others) is
capable of parsing an HTML5 document to DOM which can easily be
serialized back to XHTML, so other differences between the two
serializations can be worked out that way.
