  <!--  
   Type is a loosely defined field because there is such a lot of variation in how it
   is used.
   The principal variation is how much information that could be represented elsewhere
   is also 
   represented here. For instance, here's some possible types:
     lithium heparin plasma   (+ .container.additive) (e.g. SNOMED CT 446272009)
     transfusion bag of blood (+ container.type) 
     Peritoneal lavage        (+ collection.sourceSite)
   If the type includes other fields, it would be normal not to populate the other fields

   Note that this practice is so widespread that it's pointless to try and stop it   -->
