Many questions are in SNOMEDCT eg observable entities
Many answers are in LOINC, in particular the answers to questions for assessment scales.
ISO TS 13972 gives careful guidelines to choose the precise code from any code system for both questions and answers.
The blunt this does A and that does B will prove impossible for many concepts and I see no move to 100% redo SnomedCT nor LOINC (because it is unnecessary).

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.
