				This type definition is for service reference container.
				This container is used as envelope to wrap around the actual endpoint reference value,
				when a BPEL process interacts the endpoint reference of a partnerLink.
				It provides pluggability of different versions of service referencing schemes
				being used within a BPEL program. The design pattern here is similar to those of
				expression language.
