This should be documented in https://w3c.github.io/w3c.json.html.

@plehegar who would be the right person to fix/review this?

[plehegar]

so, we used to recommend it but we never used it. Consequently, a lot of the w3c.json still have them. Unless we do find an actual use for them, I wouldn't document them. Or at most, I put that under "unused". If you do decide to use them, then I agree we should document them properly.

[foolip]

I just noticed because I tried writing a schema for w3c.json and validating against it. I don't want to use the properties myself, but it would be a bit of work to remove them from all of those files.

[plehegar]

we never meant to be restrictive in the w3c.json, just require a minimum instead. Not sure what schema language you're using but hopefully there is a way to express that it is extensible.

[foolip]

I'm using vanilla JSON schema, so I'll just not use the additionalProperties: false bit, which is what I added to notice this.
