ObservationRange.negationInd and Criterion.negationInd are [1..1] required
- Change ObservationRange.negationInd and Criterion.negationInd to be [0..1] optional
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.
Negation is a liabilty. If not using SNOMED you still need to say it.
