| Python type: | object or None |
Value of the queryable attribute with the specified name. If one
is not defined for this object, the chain of parent dataset
collections (if any) will be searched, starting with the immediate
parent. If one is still not found, None will be returned.
None will also be returned if a queryable attribute is found but the
value of it is None. To determine whether None was returned because
the attribute's value was None or because the attribute does not
exist, use GetQueryableAttribute() to determine if the queryable
attribute exists.
