This property is the super property for all pure datatype properties that can be used to describe a gr:ProductOrService. In products and services ontologies, only such properties that are no quantitative properties and that have no predefined gr:QualitativeValue instances are subproperties of this property. In practice, this refers to a few integer properties for which the integer value represents qualitative aspects, for string datatypes (as long as no predefined values exist), for boolean datatype properties, and for dates and times.
