[regext] Picking XML namespaces

[Martin Thomson <[e-mail]>]

Folks,

I'm seeing an increase in EPP registrations for the XML namespace and
schema registries.

In the past, the names this group have selected are quite generic.

I would like to request that this group include a label in the names
that it uses.  Other users of these registries carefully scope the
names they use to avoid conflict, but this group has not done that.

I realize that there is an established pattern here that would need to
change, which is a little disruptive, but I think that it would be
respectful to other users of the registry to start using scoped names
for new registrations.

That is, in the most recent document I've been asked to review:

urn:ietf:params:xml:ns:changePoll-1.0

becomes

urn:ietf:params:xml:ns:epp:changePoll-1.0

And future documents follow the same pattern.  This is consistent with
other uses of this registry.
