tagdictionary-HasAncestor
HasAncestor is one of several possible TagRule conditions, which are used to specify a tag rule or tag validity criteria.

In the example shown, the HasAncestor condition slot has a Filter subproperty containing
the NEQL predicate which queries ancestor entries in the station: hs:ahu or hs:vav. If the Filter NEQL
predicate is true for the target object
or one of its ancestors, the HasAncestor criteria is met. If an object
is a component and has a parent component, its ancestor is that parent.
If an object is not a component or is a component without a parent
component, the endpoint of the first outbound n:parent relation is its ancestor.
