But I thought IANA did not permit duplicate paper size registrations:
na_10x15_10x15in - already IANA registered
oe_photo-s10r_10x15in - not IANA registered, but in MSN2.1
So won't they reject registering oe_photo-s10r_10x15in?

Michael,
The spec preceded any other registration so I will make sure to update the registry to include the photo-s10r size (plus any others that might be missing).
