Adding attribute to ValidationError when additionalProperties is false

[mmerce]

When additionalProperties is set to false, the ValidationError attributes don't contain the key of the attribute that violates the validation. For instance, if schema = {"foo": "string", "additionalProperties": false}, then instance = {"bar": 1, "foo": "1"} will raise the error, but there's no way of knowing that bar was the cause of it. Is there an alternative way of finding that out? We need it in order to be able to filter JSON messages according to the defined schema.

Sorry, probably wrong repo.
