Trying to validate this drm spec file

[MarianoFacundoArch]

I am trying to validate whether this drm spec file is correct or missing anything.
I want it to work with CENC, Widevine, and Fairplay. However, I am a bit lost as I can't find a proper place that specifies the correct format to support all of them.
Thanks.
