Done.

The changes based on comments on the list between the -02 and -03 version are:

* Grammar / spelling.
* Some general clarifications in the text.
* Clarification of the formulas regarding the padding length
* Registry policies changed from Specification Required to Expert Review
* Reference to RFC4347 replaced by draft-ietf-tls-rfc4347-bis-06

Robin has updated the patch for OpenSSL which is available at
http://sctp.fh-muenster.de/dtls-patches.html
to this latest version. While doing that one additional detail was addressed:
When using a reliable transport protocol, TLS/DTLS does not run timers.
So it does not make sense to introduce one just for this extension.
Therefore the last sentence of section 3 was changed from

 If no corresponding HeartbeatResponse message has been received after a user configured
 amount of time, the DTLS/TLS connection SHOULD be terminated.

to

 If no corresponding HeartbeatResponse message has been received after some amount of
 time, the DTLS/TLS connection MAY be terminated by the user.

In the OpenSSL implementation a function is provided to figure out if a HB is in-fight.
So the application can check if a HB-Response has been received anytime it wants
and can take the appropriate action.

Best regards
