I strongly disagree with this for two reasons:

1) This is creating specs with potential dead locks that become
difficult to update (imagine the W3C creating next year a new mecanism
to define IDs, you would have to update XPointer to accomodate this new
2) In a world of open specifications, I find it not acceptable to lock a
specification to use only specifications from the owner organization.
Other specs from other specifications might define IDs and I don't see
the point of blocking them.

There are cases when references need to be normative for technical
reasons, but I don't this this is the case here and making these refs
normative seems only either an editorial or a political decision!

Did you know it? Python has now a Relax NG (partial) implementation.
