Hmm... I'm interested to know what led you to take such
a detailed look at XHTML spec... you don't seem to
be as keen on studying the XML nor HTML specs...

As several have noted, that's per XML 1.0.

and that one is from HTML/SGML specs. I think there's
an editorial note about it in HTML 2.0... ah yes:

The justification for many of the issues you raise has
been given; I just want to add a bit of motivation for one of them:

As I and others have noted, that's are a consequence of basing
XHTML on XML. As to "why bother," I recommend you take a look
at the record of a meeting we had to discuss how HTML should
evolve in the face of XML, especially the issues of how
to use the DOM and CSS in HTML documents with XML-ish extensions:

	XML in HTML Meeting Report
	W3C Note 11 May 1998 
	http://www.w3.org/TR/1998/NOTE-xh-19980511

In that meeting, we discussed a variety of hacks and kludges for
dealing with XML stuff inside tag-soup-HTML; e.g.:

	Agreement on terminology: XML blocks, significant non-standard
	HTML elements (sometimes also called sprinkles), and
	crud (or real-world HTML).

What I took away from that meeting was: if you really want to use the
DOM and
CSS with HTML, especically HTML with namespace-style extensions, you'll
have
to clean up your end tags and use XML.
