Hi Jari,
  Thanks for the review. I have made most of the changes you suggested,
but I have one question.

I do not have a strong preference one way or another, but the last two
MH messages for Binding Revocation (RFC5846) and Heartbeat (RFC5847)
seem to be using a shared MH type for both the request and a response.
Let me know if you want me to change this and I will do so.

Thanks
