I agree 100%, this is a non-issue. XSLT too has to define exactly where 
AVTs can be used. Furthermore, several XForms implementations already 
implement AVTs and their authors have not reported negatively on this AFAIK.

XForms could allow a host language to use AVTs, and specify a processing 
model for those. In fact, I think that XForms should do just that in 1.2 
or 2.0 (AVTs won't be in 1.1). It doesn't mean that host languages must 
implement AVTs, just that they may do so. The benefits of AVTs are 
tremendous, in particular with XHTML. A typical use case is to update 
the @class or @style attribute on an XHTML element.
