Thanks for your suggestions for a PromptConfig.XML document.  I will bring this suggestion to the Voice Browser 
Working Group as they define the requirements and architecture for the the the follow on to VoiceXML 2.0.  
If we need any clarification about your proposal, I'll contact you.

Co-chair, Voice Browser Workin Group
