tagdictionary-HasRelation
HasRelation is one of several possible TagRule conditions which are used to specify a tag rule or tag validity criteria.
The Filter subproperty contains a NEQL predicate. If this predicate is true for the target object or a related object, the HasRelation criteria is met. A related object is the endpoint of any inbound or outbound relations where the relation Id matches the one specified in the Relation Id field. Endpoints of the endpoints, endpoints of those endpoints, and so on are also tested.
If the target object, or an object along the relation specified in the Relation Id field, has the tags listed in the Filter property and has the relation specified in the Relation Id field, then the parent definition's tag(s) may be applied.
