One of the key ideas with a standard is that one is supposed to be able to
implement it without having overheard some decision on how to represent
something in a phone meeting :-).

Thanks for providing an example, it is highly needed.
I have a few comments, but we should definitely wait to after Rio with
modifying anything.

This is not a UUID (correlationId is a uuidType). It is a URI/URN, which
happens to by a UUID. Also there is a slew of ways to represent UUIDs. I
do not see the reason for forcing the usage of UUIDs. Given the
constraints I would have choosen UUIDs myself, but forcing a specific
technology into the spec. seems a bit silly. A string would do fine as
type.

Are we just using URNs because it is possible? I have a hard time seeing
what value they add here? (they do not provide a global namespace).
