RE: Core Vocabulary round 2 reminder

Hi Jo, 

Good point. Actually, that might be why OMA picked vendor rather than
manufacturer as the term for UAProf.

I guess the question is whether or not every aspect of the delivery
context is identical, apart from the name. If there is any other
variation, then it's not the same delivery context, and the problem goes
away. DDR needs to have separate entries for both.

However, if the delivery context is identical, it suggests that the actual
name/model of the device cannot be determined uniquely from, for example,
the HTTP headers, so the value of the property is questionable anyway.
This is certainly the case for Windows Mobile devices. 

Maybe we can avoid the need to worry about synonyms by having a way to
signal that the value of a property cannot be uniquely determined?
Alternatively, a 'generic' value could be returned.

Then again, this doesn't solve the issue of queries to the DDR at design
time to retrieve properies for a particular device by name. In that use
case, it would be much better for a user to be able to ask for the
properties of a device by its usual known name, rather than having to know
the name of the OEM manufacturer who actually put it together.

Complicated isnt't it?

Cheers
Rhys
