Section 4.6 says:

   E. M:N (M, N > 1, N >= M) type:

   A set of M specific recovery LSPs/spans protects a set of up to N
   specific working LSPs/spans.  The two sets are explicitly identified.
   Extra traffic can be transported over the M recovery LSPs/spans when
   available.  All the LSPs/spans must start and end at the same nodes.

It should say:

   E. M:N (M, N > 1, N >= M > 1) type:

   A set of M specific recovery LSPs/spans protects a set of up to N
   specific working LSPs/spans.  The two sets are explicitly identified.
   Extra traffic can be transported over the M recovery LSPs/spans when
   available.  All the LSPs/spans must start and end at the same nodes.

Notes:

M > 1 is not specified

[Adrian Farrel]
M > 1 was intended by the language "M, N > 1"
This has been confused by the othe use of a comma
