All,
	This update addresses comments received during AD and IESG review.
There are quite a few editorial changes thanks to a very careful review
by Dimitri.  The technically substantive changes are the additions of
the following:

   3.3.2. Unknown Association Types

   A node that receives an ASSOCIATION object with an unknown
   ASSOCIATION type MUST forward all received ASSOCIATION objects as
   defined above.  The node MAY also identify associations per the
   defined processing, e.g., to make this information available via a
   management interface.

and

   5. Compatibility

   Per [RFC4872], the ASSOCIATION object uses an object class number of
   the form 11bbbbbb to ensure compatibility with non- supporting nodes.
   Per [RFC2205], such nodes will ignore the object but forward it
   without modification.  This is essentially also the action taken for
   unknown association types as discussed above in Section 3.3.2.
   Operators wishing to use a function supported by particular
   association type should ensure that the type is supported on any node
   which is expected to act on the association.
