decoupling from HTML

Oooh... that is definitely something that should be reopened and evaluated 
to determine a solution that covers not only HTML/XHTML but, as mentioned, 
common data feed formats + SVG, XUL, XAML, and/or any other XML format which 
in quite a short space of time will be seen more and more as the default 
markup (and as such, namespace) for a variety of "pages" served up by 
default when a particular framework (e.g. XAML) is known to be available on 
the client. In fact when you download and install the latest Indigo/Avalon 
WinFX beta release you are given the option to set IIS 6.0 to render the 
XAML version of a particular page when the client is capable and the server 
contains the proper xaml page in the directory requested by this client.

I realize that the page that is contained at the specified location does 
little more than act as a way to locate the proper validation information 
and as such can be HTML/XHTML without effecting the rest of the applications 
contained on that particular server. But there are enough justifiable 
reasons (technical and marketing) for a web server to be allowed to only 
serve, for example, RSS and Atom data feeds, that I believe this will become 
fairly common place in a fairly short period of time. In fact services like 
FeedBurner already allow the ability to host and serve up your data feeds 
and as such the requirement to actually have a public site doesnt exist, 
instead using a simple tool to create and post your entries directly to 
FeedBurner for publication.

What then?
