And I am not sure whether this document will be part of the work of the
new (SW Deployment) group. I copy this mail to Ralph, he may know.

The 'unendorsed' version is, as far as I can see, identical to what
OWL1.1 defined. Ie, I think the most stable namespace is the one in the
OWL1.1 document for that. But that would be temporary anyway...

If you want to deploy your things with the tools of today, you may want
to consider the 'workaround' alternatives, too...
