Re: EMMA in Speech API (was RE: Speech API: first editor's draft posted)

Deborah,
Since the JavaScript Speech API we're defining is new, I presume there must
be a new JavaScript "glue" layer between the Speech API and the existing
applications, dialog managers and log analysis tools that you mention. [1]
 Since the minimal EMMA wrapper you've defined is so simple, it could
easily be generated in that JavaScript "glue" layer.

I propose that we define attributes for EMMAXML and EMMAText so that
recognizers that do support these do return them, and we make it acceptable
for user-agents to return NULL for these attributes for recognizers that
don't support EMMA.

Thanks,
Glen Shires
