This is an additional section that should be added to the existing fonts policy.
Licensing Information in Metadata
The "copyright notice" field (#0) of the "name" table of TTF and OTF files MUST be populated and contain accurate information. Additionally, if information is provided in the "license description" (#13) or "license info URL" (#14) fields are populated, the information contained therein must also be accurate.
You can use the tools provided in the otfnames package to check the metadata and correct it if necessary.
