Action	Validate that: AdditionalDataJson is NULL, is empty, or contains a single valid JSON value whose root element is an object.
Description	The attribute holds the custom or optional attributes of an object, where every application or service keeps its own data under a separate top-level key. A root object is required so that an application can read its own key and preserve the keys owned by the others. Values whose root is not an object are rejected - an array, a number, a quoted string, null or true - as is text which follows an otherwise valid object. The attribute is delay loaded, so the rule validates the value only in the saves which set it. The stored value is not read from the database on every commit of the object.
Message	Attribute 'Object.Additional Data JSON' has invalid value. The value must be a valid JSON object.
Version	Introduced: v.27.1
Revocable	NO
