Yacine, Jussi:
The Diffserv PIB already IMPORT Dscp and IfDirection from different modules of
the Diffserv MIB.  So I did not think there is any issue to also reused the 
definitions
for dsTBParamType and dsIfSchedulerCapsServiceDisc from the Diffserv MIB as
advised during IESG review.

The Diffserv PIB's references to the Diffserv MIB are clearly specified as:

    dsIfSchedulerCapsServiceDisc OBJECT-TYPE
        SYNTAX      AutonomousType
        STATUS      current
        DESCRIPTION
          "The scheduling discipline for which the set of capabilities
          specified in this object apply. Object identifiers for several
          general purpose and well-known scheduling disciplines are
          shared with and defined in the Diffserv MIB.

          These include diffServSchedulerPriority,
          diffServSchedulerWRR, diffServSchedulerWFQ."

and

    dsTBParamType OBJECT-TYPE
        SYNTAX       AutonomousType
        STATUS       current
        DESCRIPTION
          "The Metering algorithm associated with the
          Token-Bucket parameters.  zeroDotZero indicates this
          is unknown.
          Standard values for generic algorithms are as follows:
          diffServTBParamSimpleTokenBucket, diffServTBParamAvgRate,
          diffServTBParamSrTCMBlind, diffServTBParamSrTCMAware,
          diffServTBParamTrTCMBlind, diffServTBParamTrTCMAware,
          diffServTBParamTswTCM

          These are specified in the Diffserv MIB."

respectively.

I believe the above text is clear.
Please advise if improvement can be made.
Thanks!
