On a general note, I think 'sequence<Grammar>' in my earlier mail should be
replaced with an array Grammar[] to match the recommended way in new web
APIs.

Being an array individual elements could be inserted/removed at will just
like calling add/remove methods.

Is the concern about the speech service updating the grammar file(s) while a
webapp is running in the client machine? I think that is specific to the
speech service implementation.
- If the grammar is provided by the same speech service, I think when the
service updates the grammar data it would also update any in memory caches
so any ongoing sessions will continue to work.
- If the grammar is provided by someone else and the speech service fetched
it over the wire at start of session, it would have caching rules as to how
long it would hold a copy before fetching again. Until it fetches again all
sessions will continue to use the old grammar data irrespective of whether
the client sets a new grammar object or not.
