"media-size" is REQUIRED while "media-size-name" is RECOMMENDED.

The way we defined them allows a Printer to support both attributes, the Client can discover what the Printer supports, and the Client can use whichever supported attribute is best. The only issue with the current wording is that a Printer can't report both member attributes in a media-col-database or media-col-ready collection.
