BGP Extended Communities Types - per [RFC-ietf-idr-bgp-ext-communities-09.txt]

In addition, this memo instructs the IANA to create two registries
   for BGP Data Collection Communities, one for standard communities and
   one for extended communities.  Both of these registries should
   initially be populated by the values described in Section 4.  IETF
   Consensus, usually through the Global Routing Operations Working
   Group (grow) is required for the assignment of new values in these
   registries (in particular, for <Value> or <R>), as described in
   Figure 2 [RFC2434].
