For measures that have a population basis that is different than the subject, this element specifies the type of the population basis. For example, an encounter-based measure has a subject of Patient and a population basis of Encounter, and the population criteria all return lists of Encounters.",
      "comment" : "For a subject-based measure, the population basis is simply boolean; all the criteria are expressed as true/false conditions that determine membership of an individual case in the population. For non-subject-based measures, the population basis can be any resource type, and the criteria are queries that return the subject's contribution to the population as a list of that resource type. For example, for a procedure-based measure, the population criteria would return lists of procedures that should be included in each population.",

Note that because the binding is to all fhir types, it is possible to specify abstract types such as Resource or DomainResource as the basis for a measure.
