scope:

Profiles the behaviour of a DSA regarding the operation of the Directory System Protocol (DSP) when communicating with another DSA, as an invoker, as a performer, or both. It also profiles the coordination of a DSA communication across several associations to perform a particular distributed operation. It also covers the behaviour of DSAs when acting in accordance with the rules of Distributed Operations (although, in this case, the interaction can be by means of returning referrals or continuation references to DUAs using the DAP protocol).
