Many use cases don't require that origin be disclosed, so I think
making a MUST requirement on origin disclosure isn't as good as making
the disclosure optional. It may be that for some intents, origin
disclosure is mandatory to make them work, but at the API level, it
ought to be optional.

I think having the origin disclosed as an 'origin' property on the
intent object, the way Conrad proposed, is a good idea. How shall the
client cause the UA to attach that field? Some options:

1. a "useOrigin: true" member of the constructor literal.
2. an "origin: xyz" member of the constructor literal.
3. Set up out-of-band by the user as a property of the registered
service. (i.e. "always disclose origin to this service" registration
option)
4. Possible exception: for explicit intents, always attach the origin.

Does (3) (and possibly 4) solve all the use cases we know about? If
so, that's the least intrusive modification to the API.
