      "This module provides a YANG data model for the routing and
     wavelength assignment (RWA) Traffic Engineering (TE)
     topology in Wavelength Switched Optical Networks (WSONs).
     The YANG data model described in this document is a WSON
     technology-specific YANG data model augmenting the generic TE
     topology module (ietf-te-topology) based on the information
     model developed in RFC 7446 and the two encoding documents
     RFC 7579 and RFC 7581.
