How closely are the two coupled? Is there information which needs to
be passed between the two?
If the coupling is not too tight, I'd say separating the two looks
nicer, as it shows that semantically they are seperat. The outer
analyzer can instantiate an instance of the inner if necessary
(i.e., if there's a body) and then call it's DeliverStream() method
for the data.

Not sure I understand that. Does this mean SDP can be encapulated
inside SIP but does not have to?
