Section 9.1 Privacy
The 2nd bullet  "User may not want to reveal that they
have accepted subscription from certain users".

I can understand if user may not want to reveal that
he has _rejected_ subscriptions from certain users. 
That's polite blocking. But I am not aware of not 
revealing accepting subscriptions. Does the user 
reject it, but the present agent actually sets up the
subscription? That can't work. We can't send NOTIFY
to a subscriber if his subscription appeared (to him) to
have been rejected.

Nits:

Section 4   2nd paragraph

o "The subcription is carried along SIP proxies as any other 
    request would be".

   "subscription" => "SUBSCRIBE request"

o "...it eventually arrives at a presence server, which can 
   either terminate the subscription..."

   "terminate the subscription" => "serves as  the 
   terminating point for the SUBSCRIBE request and
   handles the subscription"

Section 4  6th paragraph

o "This (refresh) SUBSCRIBE is nearly identical to the 
    initial one, but contains the dialog identifier, different 
    sequence numbers, and a set of Route headers..."
    =>
    "...but contains the To tag, a higher sequence number,
    and possibly a set of Route headers..."

Section 9.2
o "http" => "HTTP"
