<!--   
 This is an example of a multi-select values/answers as a single observatio using
 components to group  the multiple answers 
   --><Observation xmlns="http://hl7.org/fhir">
  <id value="alcohol-type"/> 
  <!--    the mandatory quality flags:    -->
  <status value="final"/> 
  <!--   
    Observations are often coded in multiple code systems.
      - LOINC
    - or SNOMED
      -and/or the source system may provides its own "local" code, which may be
   less or more granular than LOINC.
  In this example there is only local codes
