//Description:
//      Contains definitions for UNI-AAL interface Request (req) and
//      Response (resp) primitives. Primitives are implemented as
//	OVOPS++ messenger classes according to Visitor pattern.
//	If primitive has parameters, access methods (set and get)
//	for those parameters are defined.
