Description

Currently Atlas can use mappedFromRef constraint and the refAttribute param in an attribute to point to a child type that points back to the parent .
See 0030-hive-model.json for an example.

In an operational environment where we want to update these attributes - we want the corresponding attribute (related using the constraints) to be updated.

I suggest that we add an inSyncRefAttribute in addition to the existing refAttribute. If inSyncRefAttribute constraint is specified then the attribute pointed to is kept in sync with our attribute. On creates, updates and deletes. This will be supported for List and non List attributes.
