Thanks for the update to the document. This incorporates the outcome from some
discussions in San Francisco in real life.

I think that the partial orderings used belong in the main text of the document.
I think the following (partial ordering) relationships are used; I think that
together these define the same order as in appendix C:
  1: IPv4 < IPv6
	2: prefixes, including length, in rfc3779#2.2.3.6 order
	3: maxlength (with default value inferred)

As an implementor in a higher level language, a definition of a sort on a memory
representation can not be easily implemented. An idiomatic implementation would
use higher level abstractions (see [0]). roasort-rs seems to also use a higher
level abstraction than the memory comparison described in the draft.

Kind regards,
Ties
