This applies to Sets of SMInfo as well as Gets.

The registration interface will need to be extended somehow for this.
I don't think we want to add an attribute ID mask :-) The simplest way I
can think of is to add an issm bit to the registration request structure
and special case these unsolicited receives to go to the SM if it has
been registered and to drop otherwise.
