Review discussion on optionality and populating attribute groups:

1. Scope and purpose of syntax
   1. Extract/disentangle SNOMED CT (and SNOMED CT-relevant) content from a FHIR Condition resource (i) into a free-standing and ‘recognisable’ SNOMED CT expression, whilst (ii) ‘leaving nothing behind’ which may be of relevance to further processing
   2. Specify mappings from FHIR value sets (e.g. Condition.clinicalStatus) into SNOMED CT
   3. Transform the extracted expression into an ‘optimally-processable’ SNOMED CT expression (in particular grouping body site values with morphology)
   4. Specify constraints on what the extracted/disentangled SNOMED CT expression could or couldn’t contain (by e.g. cardinality instructions).
2. (From a(ii) and b above) Simplify |finding context| refinement to either:
   • 408729009 |finding context| = [[ @findingContext ]]
   • 408729009 |finding context| = [[ findingContextTable ($clinicalStatus, $verificationStatus) ]]
3. (From d above) How to specify cardinality in terminology binding when restricting valid values in an information model data element:
   • • 62014003 |Adverse reaction to drug (disorder)|: 246075003 |Causative agent| = [[ [0..1] ^ 111115 | AMP reference set | ]]
     • 62014003 |Adverse reaction to drug (disorder)|: !! [0..1] !! 246075003 |Causative agent| = [[ ^ 111115 | AMP reference set | ]]
4. (From c above) To indicate how the following data structure can be used to populate a template:
   • HL7 FHIR Mapping Syntax
     • Explore ....
   • Other examples discussed by email (double scope):
     • |finding| : [[ {    [0..*] |findingSite| = $bodySite << 48566001 | Bone structure of extremity (body structure) |,
           [[ [0..1] |assocMorph| = $morphology < 72704001 | Fracture (morphologic abnormality) |]] } ]]
