Simple Reference Sets can be used to represent extensionally defined subsets of SNOMED CT components, whereas the 5.2. Query Specification Reference Set are useful for representing the intensional definition of SNOMED CT subsets. In the 5.2. Query Specification Reference Set, the Expression Constraints can be used to represent the query used for defining the set. This means that the 5.2.
