    description
        "This module provides mapping between SRV6 policy identifiers (color and endpoint)
         defined in the hc2vpp-oc-srte-policy module and identifiers used by the VPP SRV6
         policy plugin. VPP uses BSID as policy identifier, which is mapped to color and
         endpoint identifiers in the model.

         The mapping is managed internally by the HC SRV6 plugin.
         It is exposed as operational state data for debugging purposes.
