> Ticket 22: R1_COUNTER inclusion in I2
> -------------------------------------

Old text:

The R1_COUNTER parameter is optional. It SHOULD be included in the R1 (in which
case, it is covered by the signature), and if present in the R1, it MAY be
echoed (including the Reserved field verbatim) by the Initiator in the I2
packet.

New text:

Support for the R1_COUNTER parameter is mandatory. It SHOULD be included in the
R1 (in which case, it is covered by the signature), and if present in the R1, it
MUST be echoed (including the Reserved field verbatim) by the Initiator in the
I2 packet.


Implications:

Making the R1 parameter mandatory requires a parameter number change from 128 to 129.

Attention:

This change requires implementations to change the parameter number.


BR,

Tobias
