While we're on the subject, I'd like to make another change -- a clarification.

section 4.3:

OLD:

   If a transit LSR recognizes the ELI, it MAY choose to load balance
   solely on the following label (the EL); otherwise, it SHOULD use as
   much of the whole label stack as feasible as keys for the load
   balancing function, with the exception that reserved labels MUST NOT
   be used.

NEW:

   If a transit LSR recognizes the ELI, it MAY choose to load balance
   solely on the following label (the EL); otherwise, it SHOULD use as
   much of the whole label stack as feasible as keys for the load
   balancing function.  In any case, reserved labels MUST NOT be used
   as keys for the load balancing function.

Kireeti.

PS: there, you see, I do (sometimes) use MUST/MUST NOT.
