[Apple Music API] What are extended attributes?

In many request you can include "extend" parameters. But there is nowhere list of extended attributes that I can apply to the request. I tried using various option but results are the same as without them.

Apple. Your documentation for both your APIs and SDKs is not workable in their current form. Developers, myself included are having to fight tooth and nail to try and implement the most basic of functionality you provide.

I implore you to document properly and at least bring the docs up to snuff with what Spotify offer in this regard.

There are so few services that actually support Apple Music for this reason so it's well within your power to increase adoption this way.

Don't be the meme of the guy who puts a stick through the front spokes of his bike.
