Nits:  1

(1) Minor:

In sections 4 & 5, one of the termination-point-types is called 
"unnumbered", and contains an "unnumbered-id". But the value contained 
here is in fact a uint32 *index* value. This clearly *is* a number. So,

I gather it designates a termination point that is identified by this 
index rather than by a name or an ip-address. If so, a better name might 
be "index" or "indexed".

(2) Minor:

The examples in section 6.2 seem very helpful. But is it really 
necessary to fill in so much detail? The amount of detail seems to make 
it overly difficult to grasp the essential features. For instance, the

(3) NIT:
