Question: Detecting keys/properties not in schema

[lmartinking]

Hi, I was wondering if it's possible to detect properties/keys not defined in the schema?

Thanks in advance!

use additionalProperties keyword with false value

"additionalProperties": false

Hello, "additionalProperties": false is exactly the behavior I want.

However I have to add it to every object in the whole schema which is tedious and error-prone. It would be much nicer if there was an option for globally strict validation by default, e.g. assume "additionalProperties": false for any object in the schema where "additionalProperties" is not explicitly set to something else.
