My understanding (but I'm a newbie) is that you send a <presence 
type="unsubscribe"> element to the person you want to remove from your 
roster. (Protocol Overview, 1.4.1.6, p.12.)

I'm basing this on the assumption that the roster is identical to the 
list of people whose presence you're subscribed to, which is true in 
other IM clients.

Well, on looking at the jabber:iq:roster description in the Protocol 
Overview, it does say that a client can add or remove roster items using 
queries with this namespace (although as you point out it doesn't say 
how.) So how does this differ from sending <presence> elements?

I'm beginning to get the impression now that the roster and the set of 
people who send me presence are two independent entities. Is this true? 
If so, how can I get an authoritative list of people whose presence I'm 
subscribed to?
