Issue

ObservationRange.negationInd and Criterion.negationInd are [1..1] required


Recommendation

  • Change ObservationRange.negationInd and Criterion.negationInd to be [0..1] optional


Rationale

Terminfo guidance and thinking in NHS/UK domain, rules out the use of negationInd when act.code contains a code from a scheme that already encompasses negation (eg SnomedCT). Currently negationInd cannot be refined out in models that mandate such a coding scheme, leading to potential inconsistency.

Discussion

Negation is a liabilty. If not using SNOMED you still need to say it.
