Yes.

Yes, and any other restrictions or permissions that might be associated
with the AS at the SGP (such as calling party address).

For SE-IPSP, the AS the message is for and the AS the message is from are
the same.  For DE-IPSP, because messages are essentially sent from the SGPF
to the ASPF in the criss-cross model, the AS is the As that the message is
for just as in the SGP->ASP case above.
