Allaw @id, @type, @context with JsonLd. With this it's possible to use the @id as described in the documentation while using allow_extra_attributes: false.
More info in #6402.

this is perfect, would you be able to add a test?

Could you also add a test that ensures an error is thrown if the value of the @id key doesn't match the URL?

I was not available but I see a test was already added.
If it's useful in any way here is a PHPUnit test (commit) of the full usecase of writableLink using @id while allow_extra_attributes: false.

Side note I see you were discussing:

If the @id line on the "Main" object is removed or id is different from the URL, the "subs" array embedded objects will behave unexpectedly (removed or throw a duplicate error). Not sure if a problem or just needs to be documented as the description in the documentation only mentions the need/behavior for the @id on the sub embedded objects and not their need on their parent too.

This could maybe be an @internal enum?

[soyuka]

too much trouble transforming an enum to an array this is more efficient imo, I could set private visibility?

thanks @ili101 !
