which means, there can even be a case of consecutive
sequences of Data-in PDUs,
with each sequence consisting of 1 PDU with F bit set.
is it so ?

  Elliot,

  Thanks .  Will change 2.7.1 to read:

  1.1.1     F (Final) Bit

     For outgoing data, this bit is 1 for the last PDU
of unsolicited data or
     the last PDU of a sequence answering a R2T.

     For incoming data, this bit is 1 for the last
input (read) data PDU of a
     sequence.  Input can be split in several
sequences each one having it's
     own F bit. Splitting in sequences does not affect
DataSN counting on
     Data-IN PDUs but MAY be used as a "change
direction" indication for
     Bidirectional operations that need such a change
and/or end of
     recoverable sequences by targets with a limited
replay buffer.

     For Bidirectional operations, the F bit is 1 both
for the end of the
     input sequences as well as the end of the output
sequences.

   Comments?
