* Section 4.1

"The value 15 is reserved for Experimental Use [RFC5226]"

I don't think this document should be reserving value 15 for Experimental
use based on its stated intentions "a LISP shared message type for
defining future extensions and conducting experiments".

RFC3692 defines the experimental values as 

"  Mutually consenting devices could use
   these numbers for whatever purposes they desire, but under the
   understanding that they are reserved for generic testing purposes,
   and other implementations may use the same numbers for different
   experimental uses."

which means that devices may use any of the sub-types under 15 for
experimentation and potentially collide with the "extension" uses.

I would propose that a sub range of the sub-types (e.g. 2048-4095) under
type 15 be reserved for experimentation and the rest of the range
(0-2047) for extensions be specified using some other IANA policy (e.g.
FCFS as specified in the document).
