Validation of properties not defined in the schema

[abunuwas]

Given a certain schema, should we invalidate payloads which contain keywords which are not defined in the schema?

For example, given a schema with the following property:

{
    "properties": {
        "property": {
            "type": "string"
        }
    }
}

Is the following payload acceptable or should be invalidated due to the presence of a property which is not defined in the schema?

{
    "property": "property",
    "invalid": "invalid"
}
