With Attribute-based subsets, the Analyst chooses a Attribute Definitions Dialog (that has been associated with objects) and then selects one or more of the enumerated members of that Attribute. When compiled, Attribute-based subsets are populated with all objects that have the specified values for the selected Attribute.
