The CREATE directive has one argument: ACCESS POINT. This argument is optional, although a Superior Reference entity without an Access Point attribute serves no purpose. You can specify the Access Point attribute using the SET directive instead. The ACCESS POINT argument identifies a DSA holding a naming context which is superior to all the naming contexts contained within this DSA. Specify the ACCESS POINT argument in the following format: ACCESS POINT <access point> where <access point> is the access point of the DSA and is specified as follows: {[ae title = "<distinguished name of DSA>", presentation address = '<presentation address>']} The AE Title and Presentation Address attributes are both mandatory. Note that you must specify the AE Title and Presentation Address in the order shown above. Specify all valid NSAPs for the DSA in the access point. This improves the network efficiency of the DSA, ensuring that if a connection to the relevant DSA already exists, it is always re-used. Refer to DSA Common_Datatypes for more information on how to specify an AE Title and a Presentation Address.
