RE: Suggestion for grammar element in VoiceXML 2.1

Thank you for your comments regarding VoiceXML 2.1. Your change request
has been rejected for the following reasons:

1. Your comments were submitted outside the Last Call period which ended
on 6 October 2006 as stated in [1].

2. As stated in the VoiceXML 2.1 specification, the expression
associated with the srcexpr attribute of the <grammar> tag "must be
evaluated each time the grammar needs to be activated." This allows, for
example, grammars to be conditionally enabled or disabled at run-time.

Subject: Suggestion for grammar element in VoiceXML 2.1


VoiceXML 2.1 specification extends the <grammar> element to support
dynamically generated URIs for grammar.(by addition of 'srcexpr'


I suggest that the same should only be allowed for formitem level
grammars. Otherwise for all the grammars declared at dialog scope (or
above), the URI has to re-evaluated and the grammar has to be defined
again for each input item. This actually defies the concept of keeping a
grammar at dialog level.

Also, am not able to find any use case to have the same (at dialog level
or above) in any VoiceXML document.


Since, this is not added as a restriction in VoiceXML2.1 specification,
all the compliant processors will anyways has to support this. So, this
can be added as a restriction for grammar element with 'srcexpr'


  Please let me know about your comments on this.
