I support Rob Wilton's DISCUSS position.  Piling on a bit, in reference to:

   R6.  UDP requestors SHOULD limit the requestor's maximum UDP payload
   size to the RECOMMENDED size of 1400 or a smaller size.

I think the "RECOMMENDED" here is just carrying forward a "RECOMMENDED" from
someplace else.  If that's correct, I suggest changing it to "recommended" or,
if you want to be more precise, "... to the size recommended by RFCXXXX of 1400
or smaller."  Now it's clear what the SHOULD is referencing, and you don't own
the RECOMMENDED part here.

I suggest defining "EMSGSIZE" in Section 2 to be the UNIX error code of the
same name.  Otherwise, we encounter it in Section 3.1 in a way that could mean
it's an error code (which is how I think you intend it) or as a symbolic name
for the path MTU size.
