This seems like unnecessary bits-on-the-wire for the CUA. Shouldn't the CUA
just query the CS and respond accordingly?

What scenario did you have in mind that necessitated the CUA to also specify
it's capabilities? Just because I have a capability doesn't mean that in a
given session instance that I am going to use it. So what good is it to the
CS for the CUA to provide this input?

Can you give us an example?
