Sorry, i did not read the text that carefully (rather only Dean's
question)

My previous comment was about the default mode if client won't give any.
In 04 it was "xcap-patching" but it can be any of those, and Dean
proposed "no-patching" which is fine.

Right, the last sentence in 4.3 is _wrong_. The subscribers MAY
implement any of the modes, but it doesn't need to support patching at
all. The same applies to the notifier with the exception that it MUST
implement xcap-component subscriptions. The last sentence of the first
chapter of 4.3 is also wrong since the client could only subscribe to
xcap component changes, so it'd better to remove the last part ", as all
subscribers are required to support that mode."
