Isn't the html generated already XHTML compatible?  I remember vaguely
this issue, but not the conclusion.  Instead of a new command line, it
could also be a customization file like those that are in tp/init/.

(In my opinion, doing HTML5 would probably be more interesting than
XHTML...)

If this is better than the current HTML generated, it can easily be
changed.

If it is not to be used in the default HTML output, doing such
customization should be easy with an init file.  This is not documented,
however and the API has never been stabilized.  There is an example in
tp/init/html32.pm which allows to produce valid HTML 3.2.
