2.12.10 Subobject Restriction Structures
The SubObjectRestriction structure, as specified in section 2.12.10.1, applies its subrestriction to a Message object's attachments table or recipient table. If any row of the subobject satisfies the subrestriction, the message satisfies the SubObjectRestriction structure.
The SubRestriction_r structure, as specified in [MS-NSPI], is an encoding of the SubObjectRestriction data structure. The semantic meaning is unchanged from that of the SubObjectRestriction data structure.
