In draft-kelsey-intarea-mesh-link-establishment-03.txt it says that 
   MLE messages are sent using UDP.

I want to suggest that MLE messages should be sent at least as IPv6
ICMP messages.  

Further, I think that it could use the RPL type 155, and RPL would
allocate a new "code" codepoint.

There would be some preference to have the general structure of MLE
match that of RPL, but I think that this isn't particularly a strong
requirement.   Allocating a new ICMP type code for MLE alone might be
seen as excessive, but I can not speak for the folks in 6man.
