Relation pm#how_much_relation (*)
  supertype:  how_relation__howrelation
  subtype:  duration (situation -> time_measure)
  subtype:  relation_to_attribute_or_quality_or_measure (*,attribute_or_quality_or_measure)
     subtype:  attribute (?,attribute_or_quality_or_measure)  e.g., [a car, attribute: a weight]
        subtype:  property (?,Attribute)
           subtype:  attribute (object,Attribute)  the 2nd argument is an attribute of the 1st
           subtype:  manner (process,Attribute)  the 1st argument is qualified by the 2nd (which is usually denoted by and adverb), e.g., the speed of the wind, the style of a dance, or the intensity of a sports competition
        subtype:  qt__quality (quality_or_endurant_or_perdurant,quality)  the DOLCE predicate qt(x,y,t) means "x is a quality of y" but this relation respects the usual reading conventions: the 1st argument has for quality the 2nd argument
           subtype:  direct_quality__dqt (quality_or_endurant_or_perdurant,quality)  the DOLCE predicate dqt(x,y,t) means "x is a direct quality of y" (not a quality of a quality of x) but this relation respects the usual reading conventions: the 1st argument has for direct quality the 2nd argument
     subtype:  relation_to_another_attribute_or_quality_or_measure (attribute_or_quality_or_measure,attribute_or_quality_or_measure)
        subtype:  measure (attribute_or_quality_or_measure,attribute_or_quality_or_measure)  e.g., [a weight, measure: 75 kg]
        subtype:  q_location__qlocation (quality,region)
           subtype:  has_quale__hasquale__ql (quality,quale)
     subtype:  has-unit-of-measure (physical_quantity,unit_of_measure)
  subtype:  relation_from_collection_to_number (collection -> number)
     subtype:  size__number_of_elements (collection -> nonnegative_integer)
        subtype:  length (list -> nonnegative_integer)
     subtype:  minimal_size__minimalsize (collection -> nonnegative_integer)
     subtype:  maximal_size__maximalsize (collection -> nonnegative_integer)
     subtype:  percentage (collection -> number)
     subtype:  average (number_container -> number)  to specify an average on the values
