[JDEV] Error Message

[Jamie Warner]

Hello,
    I'm working on presence subscriptions and I ran into a slight
issue.  If a user requests to subscribe to the presence of himself (I
did this accidently), the server should return an error.  I see that IQ
has the capability to return errors, but need a little guidance as to
how to form the error to send back to the client.

EX:
CLIENT: '<presence to="test at test.com" from="test at test.com"
type="subscribe"/>'

Maybe this isn't an error, and I'm just confused.

Thanks,
Jamie
