I think thats a major issue with this draft. The draft currently
defines various options and possibilities for the different points
(like encapsulation, routing, discovery, etc.). This also leaves
a wide variety of options for implementations. Therefore I see
the risk with implementations which are not interoperable (even
if those implementations are compliant with the draft). From my
point of view the draft should clearly state which options are 
required for an implementation.

  best regards
