The Simple type Reference Set serves a specified purpose for which a set of components can be specified for inclusion or exclusion.
This type of Reference Set represents an extensional definition of a subset of SNOMED CT components, therefore it can be used to fully enumerate a subset of concepts, descriptions, or relationships.
In Snow Owl you can choose from the following referenced component types:
SNOMED CT Concept
