INET-Addresses not used in MPLS MIB Modules

["Wijnen, Bert (Bert)" <bwijnen@lucent.com>]

For various cases, they cannot use the INET-ADDRESS-MIB
definitions. They were using different mechanisms at 
different places, which is not good. So I suggested that
if they can indeeed not use the INET-ADRESS-MIB TCs, that
they define their own TCs that every MPLS mib module can
re-use. It is actually more TE (Traffic Engineering)
related than pure MPLS... but ok...

Seems they too RFC2851 as an example, and maybe not 3291.

This is what they came up with. Any further comments?

                 context of an TeHopAddressType value.  The
                 TeHopAddressType object which defines the context must
                 be registered immediately before the object which uses
                 the TeHopAddress textual convention.  In other words,
                 the object identifiers for the TeHopAddressType object
                 and the TeHopAddress object MUST have the same length
                 and the last sub-identifier of the TeHopAddressType
                 object MUST be 1 less than the last sub-identifier of
