3.1.4 Higher-Layer Triggered Events
Higher-layer protocols use this protocol by creating Session Factory objects. When an active Session Factory object is created, the NfpService MUST ensure that its local Service Descriptor (section 2.2.9) is published to the transport. Higher-layer protocols like the Near Field Proximity: Sharing Protocol [MS-NFPS] can also register to handle launching of applications that can use the created socket connection. The implementation for this is not specified.
