Dear William,

I persist.
Questions -> LOINC
Answers   -> SNOMED
Check with Stan Huff for the opinion of CIMI

Yes, SNOMED has Observable entities attached to a ‘value’.
It is used in the leaf-node (ELEMENT)

Other nodes in Archetypes (all other structural classes like COMPOSITION,  SECTION, ENTRY, CLUSTER) had better use LOINC.
