The problem is that if there are multiple namespaces, or if you've also
got to include references from within other objects such as list, then
you've got to write all that somehow on the parcel tag, instead of just
having different places the arrows can start from.

The box and arrow model easily extends to this, and the fact that no-one
can make up their mind on what to *call* the thing the arrows represent
doesn't mean they don't exist.
