There absolutely is, you are right, or any other non-standard XML 
document.  Any non-html-variant application that wants to leverage re-use 
of forms.  But I'll state again, that while the spec does give a bit of 
service to other clients such as voice browsers, there are enough hints of 
HTML to suggest it's still biased strongly this way, and that there hasn't 
really been a complete clean-slate approach that would be free of these 
kinds of "idiosyncrasies."  Yes, they are covering the bases of the largest 
likely potential platforms, but they are also (IMHO) making it in such a 
way that it resists breaking free into new kinds of interfaces.

Anyway, I won't go over all of my previous issues again, but I'll just say 
I agree with you 100%, and the problem you cited isn't the only one in the 
spec that would present problems to a "non-head/body structure XML document."
