Folks, this e-mail list is intended to report problems with VoiceXML and 
related speech application langauges to the attention of the W3C Voice 
Browser Working Group.  While your discussion is interesting, it is 
outside the intended scope of this e-mail list.  I'd appreciate your 
moving this discussion to another list.

Thanks,

Jim Larson
Chair, Voice Browser Working Group
