Hi Greg,
	Thanks for the comment.  Sorry about the overdue response.

The proposed revised text to address you comment is:

      ... describes the application of linear protection to
      unidirectional P2MP entities using 1+1 and 1:1 protection
      architecture. For 1+1, the approach is for the root of the P2MP
      tree to bridge the user traffic to both the working and
      protection entities. Each sink/leaf MPLS-TP node selects the
      traffic from one entity according to some predetermined
      criteria.

      For 1:1, the source/root MPLS-TP node needs to identify the
      existence of a fault condition on any of the branches of the
      network.  Fault notification happens from the node idenifying
      the fault to the root node and from the leaves to the root via
      an out of band path...

I think this covers it.  Do you agree?

Lou
