Thanks for the updates for the various route-target,origin and site of
origin extended community types.  I'll try to take some some to read the
regex in detail.

My lingering issue with the route-target types is that IETF work on VPNs
will continue to add extended communities to have route-target semantics
outside of the types originally defined in RFC 4360.  The current example of
this is the ES-Import community.

I believe we either need to:
1. Provide a generic format for types other than 0,1,2. Or,
2. Document how the relevant type is intended to be maintained.

For example, the module that route-targets is part of is not IANA
maintained.

If this issue is still unclear, let's plan on spending a small amount of
hallway time discussing this in Prague.
