Hi Ted,

TL;DR: Yes, but this seems like a reasonable step forward from our earlier 
discussions, and IMO more detailed review is appropriate at this juncture.

Mo and I had some moderately extensive discussion of this about the time of the 
provisional registration.

I haven't yet had a look at the latest draft, but in the circumstances it seems 
to me to be a reasonable step forward.  If I recall correctly, I was previously 
a bit concerned about permanent registration of a scheme for which there was no 
freely available specification, so at the time we settled for provisional.  Or 
something like that.

Since then I've got a better sense of the scope of use of this scheme, and Mo 
has made a fair case for "promotion" to permanent status, *provided* there are 
no problems raised by community review (and in the face of problems, permanent 
registration with caveats might yet be an appropriate course).

That said, I'm sure Alexander will be more than happy to feed back any constructive criticism of the scheme itself via the DVB TM-GBS group to help shape future editions of the standards.
