Description of problem: qpid.msg_sequence in "Exchange Declaration Parameters" section (Section 2.2) has wrong / confusing description. In particular this sentence is wrong: "The sequence number for the first message sent to the exchange is 0, .." Three changes are relevant: 1) Replace 0 by 1. As the very first msq_sequence in a message is really 1 (to check this, see Exchange::PreRoute::PreRoute method where parent->sequenceNo++; is called before setting msg_sequence to a message). 2) Replace "to the exchange" by "from / by the exchange". As msg_sequence is inserted to messages "leaving" the exchange, not arriving the exchange. 3) ??? "message sent" -> "message routed" as technically the exchange does not _send_ a message, it "just" routes them to queues. But changing this can cause some confusion to a reader so I am not sure if it is linguistically ok.. Also it makes sense to add there a notice that qpid.msg_sequence is reset to 1 when qpid broker is restarted.
