RE: Incremental recognition, Unobtrusive response

Thanks for sharing that info about the proposed external events module,
Jim. When the draft mentions how disruptive external events might be to a
flow, I would guess most of that complication would arise for catch's
outside of a grammar element. Does that sound right?

After reading that draft, it seems to me that Dirk's partial tag might be
subsumed by a catch of an 'externalevent' with an inner 'if' to check what
the event is, and whether other recent events merit an (unobtrusive)
response. And if the response doesn't require jumping out of the active
grammar, we could continue getting partial interpretations this way.

Jim, you also rightly point out that unobtrusive responses slightly alter
the context for the user and may therefore require a change in grammar. I
suspect, though, that language models could be trained with optional
changes in context midway through training examples. What do you think?

Thank you, Deborah, for sharing the Semaine project; I hadn't heard of it.
I'm planning to do a comparative analysis of the three projects for Dirk's
doc.

Cheers,
David
