There are no constraits on the suffix, you are free to choose any filename.
More correctly any URI, when we are talking about the web - as long as the
URI is valid, which is beyond the scope of the (X)HTML specs.

The content-type is important. For XHTML documents it must be
application/xhtml+xml (or text/html, if is it XHTML 1.0 App. C conforming).
If you are using static files on your webserver and no special server
configuration, then the server will probably send 'application/xhtml+xml'
only for .xhtml files. Thus, if anyfile.htm contains XHTML 1.1, it would
end up invalid. But this could easily be changed without changing the URI
by tuning the server config.
