    "This model defines Yang model for OSPF routing policy.

     This model reuses data items defined in the IETF YANG model for
     routing policy by RFC9067.

     Some attributes which are not required in Open ROADM MSA are removed.
     Yang file included are changed to fit into Open ROADM MSA yang structure.
