Sending ABORT upon receipt of INIT-ACK

TO whom it may concern:

Section 3.3.3 of RFC 2960 states:


      If the value of the Initiate Tag in a received INIT ACK chunk is
      found to be 0, the receiver MUST treat it as an error and close
      the association by transmitting an ABORT.

I'm just curious what the thinking is regarding sending an ABORT.  The
server has retained no knowledge of the connection. So when it recieves
the ABORT, it will be considered "out of the blue".  So ... Whats' the
point.  In other error scenarios for processing INIT-ACK, the RFC
states:

      Note: A receiver of an INIT ACK  with the MIS value set to 0
      SHOULD destroy the association discarding its TCB.

This seems more appropriate.
