You are right, I will change it.  Thanks for the review.

>Is the following valid request-response sequence in that case

I believe so.

Hi,

I have two questions here

1. The description for Q2 state for Session says "at least one connection"
    "is XPT_UP"

    A connection goes in XPT_UP state means that only the TCP connection
    is established and no login PDU is received.

    In this state, it is not possible for a connection to belong to any
session
    as such (It is possible only after receiving the first login PDU which
means
    the connection goes into IN_LOGIN state.

    So the description for Q2 state should be "at least one connection is
    IN_LOGIN"


2. The specification says that it is possible to split a key value pair across
    multiple Text PDUs.

    Consider a case where only one key value pair is to be sent by the
initiator.
    How should the target respond to it ? Is the following valid
request-response
    sequence in that case

    I  -> T  Text Request with partial key=value pair F=0
    T -> I   Text Response empty F=1
    I  -> T  Text Request with remaining key=value pair F=1
    T -> I   Text Response for the key=value pair F=1.

Rahul
