We specify the logical address of a service and we let the underlying infrastructure determine how the message will end up there. The P2P network, for example, will determine which particular transport endpoint is going to be used. The actual transport address may be discovered after many-many intermediaries. We may also have application domain-specific registries that map logical addresses to transport-specific addresses. I would be seriously worried if such scenarios were not allowed by WS-Addressing or if the spec prescribed only a limited number of ways that transport address information was conveyed.
