(Don't you love it when people cite their sources?)

Well, Aaron, it looks like you're right.  But I have to admit I've
never actually seen this done.  In particular, Yaz's generic front-end
server only provides for a single diagnostic to be returned.  I don't
think restricting to a single diagnostic is an unreasonable
simplification to make in the ZOOM API, but I am open to be persuaded
otherwise -- particularly by anyone who's actually implemented a
server that returns multiple diagnostics (or indeed run a client
against such a server).
