I think that as a problem statement,
these initial documents need to describe
the perceived issues which motivate our
work.  I guess that in most situations,
descriptions of possible implementation
strategies aren't required for this.

In the current situation though,
I guess it's OK to have here since the
information provided is at a theoretical
level rather than tied to existing proposals.

Does anyone else have an opinion on this?

Oh, I think I see.

I was thinking in terms of interoperation with both modified and
unmodified nodes.

It may be appropriate to mention both requirements/goals here.

" A router which has been modified for DAD optimization should
  not interfere with hosts operating correctly. In particular, a router
  has to interoperate with both the host modification for DAD
  optimization as well as unmodified nodes."

If you think this would be best handled in a different requirement
(or is covered by another one) maybe this is not so important to
have here.
