Description

While looking at theVoterInterface::vote function, it was rather hard to figure out why$attributes is anarray (and what is it expected to contain):

It looks like this should be removed since Symfony 6.0:

I could not find any issue about this in the backlog.

I think it is also the time to update$attributes to astring, but that is a breaking change. This may not be possible, see#54060 (comment).

Example

interface VoterInterface{publicfunctionvote(TokenInterface$token,mixed$subject,string$attribute):int;}
