      AllergyIntolerance.reaction.certainty is-modifier = false (no change)

      Reason: part of the definition of AllergyIntolerance.reaction.substance says it must be clinically safe to only process the 'code' and ignore the 'reaction.substance'

      1) AllergyIntolerance.reaction.certainty should be an is-modifier = true element

      Per QA 5c: Ensure all elements (and only those elements) that could change the interpretation of other data are marked as "isModifier"

      http://wiki.hl7.org/index.php?title=DSTU_QA_Guidelines

      2) Since AllergyIntolerance.reaction.certainty is optional (minOccurs = 0), we should define a default value if not populated and is-modifier

      Per is-modifier guidance, "Wherever possible, elements labeled "Is-Modifier = true" also have a minimum cardinality of 1, or a default value, in order to introduce certainty in their handling"
