name: Quantity
type: null
elements:
  value: {short: Numerical value (with implicit precision), comments: The implicit precision in the value should always be honored. Monetary values have their own rules for handling precision (refer to standard accounting text books)., type: decimal, isSummary: true, index: 0}
  comparator: {isModifier: true, short: < | <= | >= | > - how to understand the value, comments: 'This is labeled as "Is Modifier" because the comparator modifies the interpretation of the value significantly. If there is no comparator, then there is no modification of the value.', type: code, meaningWhenMissing: 'If there is no comparator, then there is no modification of the value', isSummary: true, index: 1}
  unit: {short: Unit representation, type: string, isSummary: true, index: 2}
  system: {short: System that defines coded unit form, type: uri, isSummary: true, index: 3}
  code: {short: Coded form of the unit, comments: 'The preferred system is UCUM, but SNOMED CT can also be used (for customary units) or ISO 4217 for currency.  The context of use may additionally require a code from a particular system.', type: code, isSummary: true, index: 4}
