Further more, the trick in getting XForms right -- and this is
what makes it non-trivial -- 
is to ensure that XForms can both host and be hosted in other
languages. So in general it doesn't make much sense for the
XForms spec to pretend that AVTs will never show up --  basically
if the language in which XForms is hosted supports AVTs  --- say a  future
version of Open Office for instance,  then XForms will
automatically get AVTs in it. I'm not suggesting that Open Office
is certain to have AVTs; I'm just using it as an example.
