	So, I think we are saying the same thing. ebXML-compliant applications
	would be aware of the collaboration and of the CPA...

	well, my issue is not only what you raise.
	In some way, the BP describes a collaboration between two parties. Each
party
	has its own legacy software that would implement the actual execution of
the
	parts of the collaboration pertaining to the relevant role. Does not
matter,
	IMHO, if a party uses an "existing legacy" or creates a brand new legacy.
	The BP describes the collaboration, not the legacy, IMHO ! So, I imagine,
	the Registry will be filled with collaboration model instances, not with
	legacy application model instances !

	In the CPP doc, line 334, what is written is :
	"The Collaboration-Protocol layer is the interface between the CPA-defined
	business transactions and the business-application functions that actually
	perform the business transactions. "
	So, if the business-application functions also include the CPA-aware parts,
	it would read as if the Collaboration Protocol layer would interface the
	CPA with itself.
