Hi Bob, all,

I do still don't understand the intent of this field:  

   o  Tag: tag a packet as part of a class or group of packets, e.g.,
      packets sharing the same set of properties.  When tag is not used
      at source it MUST be set to zero on transmission.  When tag is not
      used during SRH Processing it SHOULD be ignored.  Tag is not used
      when processing the SID defined in Section 4.3.1.  It may be used
      when processing other SID types which are not defined in this
      document.  The allocation and use of tag is outside the scope of
      this document.

In the absence of a clear definition of this field, it is better to set these bits as unassigned. 

Cheers,
Med
