  // This method receives a single request message, executes it, and

  // is SOMD_NO_WAIT, the call will immediately return "SOMDERROR_NoMessages"
  // if there is no message pending.

  // Repeatedly calls execute_next_request.  If waitFlag is SOMD_WAIT,
  // the call will continue to wait for messages when there is no message

  void change_id(in SOMDObject objref, in ReferenceData id);
  // This method changes the ReferenceData associated with the object
  // identified by "objref".  The ReferenceData previously stored in the
  // SOMOA's reference data table is replaced with the value of "id".
  // The new id value cannot be larger than the maximum size of the
  // original ReferenceData (usually specified as 1024 bytes).
  SOMDObject create_constant(in ReferenceData id, in InterfaceDef intf,
                             in ImplementationDef impl);
  // This method is a variant of the "create" method.  Like "create", it
  // creates an object reference for an object (with the specified interface)
  // and associates the supplied ReferenceData with the object reference.
  // The ReferenceData can later be retrieved using the "get_id" method.
  // Unlike "create", this method creates a "contant" reference whose id 
  // value cannot be changed.  (See "change_id" below.)  This is because
  // the id is part of the object reference state, versus stored in the 
  // SOMOA reference data table.
  //
  // This method would be used whenever the application prefers not to
  // maintain an object's ReferenceData in the SOMOA reference data table. 
  SOMDObject create_SOM_ref(in SOMObject somobj, in ImplementationDef impl);
  // This methods creates a simple DSOM reference (SOMDObject) for a local 
  // SOM object.  The reference is "special" in that there is no explicit
  // ReferenceData associated with the object.  Also, the reference is
  // only valid while the SOM object exists.
  //
  // The SOMObject can be retrieved via the get_SOM_object method.
  // The SOMDObject::is_SOM_ref method can be used to tell if the
  // reference was created using create_SOM_ref or not.
  SOMObject get_SOM_object(in SOMDObject somref);
  // This method returns the SOM object associated with a SOMDObject
  // reference created by the create_SOM_ref method.
