This is correct, except that it is OASIS who submits them to IANA.

After having thought about this for a while, I agree.

At least the extensions for documents that do not contain foreign 
elements should remain the same.

And for those that contain foreign elements: Well, I'm not sure whether 
one mimetype would be really sufficient. A vendor A may want to differ 
documents that use its own foreign elements from the documents that 
contains other foreign elements. So, every vendor may actually want to 
register its own mimetypes and extensions.

Please note that this is permitted anyway, regardless whether we define 
a "loose" conformance mode or not.

I would like to keep the questions whether there should be an 
extensibility mechanism for *-properties separate. For details, see one 
of my previous mails.
