Yes that is that part of the VXML specification that I am referring to.  

I am sure that the browser vendors must be members of this list.  I would be interested to hear whether or not they *fully* comply with the specifcation in this regard.  Complying while maintaining recogniser independance would seem to be a non-trivial task to me.

Are you refering to the rules defined in 3.1.4 of the VoiceXML 
specification?  I'd be a little surprised if someone claimed to support 
VoiceXML 2.0 and didn't support them.  Implementation *should* be 
independent of the speech recognizer, but I can imagine there might be 
instances where a recognizer has limitations which make it difficult or 
impossible to implement for the browser (if the recognizer only supported 
a single active grammar, for example)
