Hi Ben, all, 

Thank you for zooming on these two points. 

Please see below.

[Med] We made this change:

OLD:
   tsid:  Telemetry Setup Identifier is an identifier for the DOTS
        telemetry setup configuration data represented as an integer.
        This identifier MUST be generated by DOTS clients.  'tsid'
        values MUST increase monotonically (when a new PUT is generated
        by a DOTS client to convey new configuration parameters for the
        telemetry).

NEW:
   tsid:  Telemetry Setup Identifier is an identifier for the DOTS
        telemetry setup configuration data represented as an integer.
        This identifier MUST be generated by DOTS clients.  'tsid'
        values MUST increase monotonically whenever new configuration
        parameters need to be conveyed by the DOTS client.

(also tweaked a similar text for tmid)

I hope this removes the confusion.
