Thanks for the explanation. I understand the need for
pragmatic solutions for other SDOs. I wonder though whether it
wouldn't be better to be explicit in the base documents, perhaps
by labelling the ranges concerned as "Vendor-Specific or
SDO".  It's particularly strange to tell another SDO that its
usage is "private". However, this clearly isn't a problem
that draft-sun-dime-itu-t-rw can fix.
