Inclusion of InstanceLocation for required and additionalProperties errors about jsonschema HOT 2 OPEN

i guess instanceLocation should point to some thing that is present in the input json document.

if a required property is missing, the instanceLocation pointing to that missing property when evaluated on input document it evaluates to nothing.

from jsonschema.

The instance location for required should be the object that's supposed to contain the required properties, rather than individual properties. The actual missing properties would have to be listed in the message.

The instance location for additionalProperties should be the instance object that failed against the subschema. At least I'm pretty sure of that — I'm not an expert on the output requirements.
