I guess only the minutes know then. Or the drafts.

That text has been present in one form or another since the 20
September 2007 draft.

I think it's ok. You can leave out the p:xpath-context entirely which
makes the connection implicit.

I think the prose in 4.4.1 is pretty clear that it's not an error.
