Subject: partial reliability and message fragments

Hi All

Have a question regarding PR extensions and SCTP message fragments.

If a fragment SCTP message times out in the middle of the transmission, should
the timed out fragments be sent or not?

For example, a user sends a large message that gets fragmented into 3 SCTP chunks.
After sending the first 2 of the chunks, the message expires.  Should the last chunk
be transmitted as new even though it's now "abandoned"?

Thanks
