> Good point... I could just remove the term relID, making it "The part in which a given relationship is used"?

This definition rather suggests relationships parts to me.

Part 2 already has:

	relationship   The kind of connection between a source part and
	a target part in a package. Relationships make the connections
	between parts directly discoverable without looking at the
	content in the parts, and without altering the parts themselves.
	(See also Package Relationships.)

One could argue that this is already good enough.  But here is another possibility.

	Source part 
	The part from which a connection is established by a relationship.


Cheers,
