Hi Chris,

For questions relating to the implementability of the spec, it might be
useful to check out the some of the public implementation reports submitted
to this archive.

Best regards,

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)
