Hi, just for clarification, you have mixed are two different things: - SNOMED CT postcoordinated expressions are structured combinations of one or more concepts to express a clinical idea. You use them to create new concepts not available in the SNOMED release. They are built using the SNOMED CT Compositional Grammar. In the archetypes they could be used for the semantic binding of the structure (atNNNN codes), or for data values in coded data types https://confluence.ihtsdotools.org/display/SLPG/SNOMED+CT+Compositional+Grammar
- SNOMED CT Expression Constraint Language is an extension of the compositional grammar that allows building SNOMED CT subsets intensionally, i.e., by restriction or querying. This allows you to create a subset by defining an expresion. This can be used to constraint coded values (acNNNN codes) https://confluence.ihtsdotools.org/display/DOCECL/Expression+Constraint+Language+-+Specification+and+Guide Now, if your question is about how to combine the modeling of archetypes and the modeling of SNOMED CT expressions, this paper could give you some hints. It's old, but still relevant. There are clear areas for modeling information as archetypes or with terminologies, but there is also a grey area where both solutions are applicable.
