The validate-code 'abstract' parameter is optional. Usually when a boolean is absent we consider the default to be false which - in this case - would suggest that any abstract concept passed in would be rejected.
17 Nov: Group conclusion to note "default = true" as not being ideal and that the parameter does not have much bearing on SNOMED CT as all concepts have varying levels of abstraction. No further action required. As SNOMED has no way to specify whether a concept is abstract or not, our recommendation is that this parameter is ignored in the context of a SNOMED code.
