Written by hand from the outline of Part XIV, not generated: tools/generate-schemas.mjs keeps this folder and lists none of it in index.json. In 0.1, provenance and anchors are members a detail item's schema does not know, kept at any depth; a validator holds them to this schema only when asked for the proposal (@openeik/tools: proposals [\"drawings\"]).",

  "description": "A detail item of a view (Part II, 10; drawings/detail-item.schema.json), with the two members Part XIV, 3 adds (proposed for 0.2): provenance, who made it (provenance.schema.json), and anchors, its references tried in order. The members that hold a feature and a position in the feature's frame are to be fixed with the reference implementation's anchor work (XIV.3.3): the anchor here is provisional, an element, a named feature and a position [s, t].",
