Schema: support validation/referential integrity for `objectid` types

[inactivist]

This raises a related feature: Support for a list of objectid types validated against some collection (all objectid items in the list must exist in some collection.

Should this require writing a custom Validator? (Using a custom Validator may be the correct solution, but I don't know enough to decide.)

This case could be handled in the application using a callable validation function if that capability exists.

Thanks, this is needed indeed. I'm going work on it in a few days, as soon as I'm done with the first documentation draft.

Working on this now.

How about somethig like this:

'owner': {
            'type': 'objectid',
            'required': True,
            'data_relation': {
                'resource': 'people',
                'field': '_id'
            }
        },

At the cost of a little complexity The data_relation keyword would allow to specify both the parent collection and the linked field, allowing for some flexibility (you can reference non-primary key fields).

That looks like a simple and workable solution.
