Hi Christoph,

Yup, indeed a nice advantage.

One comment:

In the "BGP Transitive Extended Community Types" registry the
'Registration Procedures" for 0x80-0x8f	list 'Reserved for Experimental Use'

However, when we zoom in on for example the 'Generic Transitive
Experimental Use Extended Community Sub-Types' registry, the listed
'Registration Procedures' are either 'FCFS' or 'IETF Review'.

To me this appears as an internal inconsistency, where I'd assume the
'most specific' procedure to take precedence? (but ... assumptions ...)

I think your draft makes sense and should proceed, but it is not clear
to me whether it would materially changes the currently listed
procedures.

Is there an internal inconsistency or am I reading it wrong?

Kind regards,

Job
