  "description": "What kind of document a Composition is, at the coarsest useful level: an authored note, a generated\nsummary, or a letter. Three LOINC codes, and they enumerate the axis.\n\n**This is the element a consumer switches on.** Bound `extensible` to `Composition.type` only.\n`type` is 1..1 in base R4, so it is the only element guaranteed present on every Composition, which\nis why the one distinction every consumer needs lives there.\n\n**The refinement underneath is `Composition.category`**, which uses `nexus-composition-kind`: which\nkind of note, which kind of summary. That set is a superset of this one, so a producer with no finer\nkind than the class may simply repeat the `type` code on `category`, or leave it absent. A section is\na third question again, and uses `nexus-composition-section`.\n\n**Extensible.** A code outside these three is nearly always a refinement written into the class slot,\nand warns. Nothing is rejected, so a document that genuinely is none of the three stays conformant.\n\nSupersedes `nexus-emr-note-classification`, which named and enumerated only notes.",
