	I will echo Michel's sentiment that the names are
	not something we should spend time discussing.

	They only have meaning to us as he describes.

	And I would go further than he to suggest that
	it is to our advantage to AVOID any existing names
	in favor of meaningful & (possibly) verbose names
	of our own.  That way we avoid tying ourselves to
	any existing & possibly different concepts.

	The mappings to existing names or to existing
	similar concepts (& how they differ from our own)
	becomes a good topic for an informative annex.
	But not something we need to concern ourselves
	with now.
