Fair enough.  I think we've agreed that the spec. is not nearly as clear 
as it should be on the whole architecture surrounding this.  I suppose I 
was trying to say that its intentions seem pretty clear to me, at least in 
this somewhat limited but very common case.

Well, it's a bit odd to claim that the spec is clear because it contains a
non-normative note that claims the spec is clear, rather than pointing to
the normative text that is claimed to be clear... 

If the spec really were carefully worded, then it wouldn't be necessary to
say so.
