The OM class DS_C_ADDRESS represents the address of a particular entity or service, such as a DSA.
It is an abstract class that has the OM attributes of its superclass, OM_C_OBJECT, and no other OM attributes.
An address is an unambiguous name, label, or number that identifies the location of the entity or service. All addresses are represented as instances of some subclass of this OM class.
The only subclass defined by the DCE XDS API is DS_C_PRESENTATION_ADDRESS, which is the presentation address of an OSI application entity used for OSI communications with this subclass.
