Chiba supports AVTs in its latest Core for the reasons you pointed out. 
It's already common and intuitive for many XML authors.

And i agree also that this will stimulate interest of authors to have 
the same in other contexts. Why? Cause it would just be so useful to 
have. I would appreciate if the WG would consider and specify such an 
extension.
