openehr-rm 0.0.2

//! Hand-written RM class invariants for `OBSERVATION`.
//!
//! Mirrors archie's `Entry` (non-terminology) + inherited LOCATABLE:
//! - `Is_archetype_root`: an ENTRY is an archetype root, so `archetype_details`
//!   must be present.
//! - `Archetype_node_id_valid`: `archetype_node_id` non-empty.
//!
//! NOTE: archie's `Entry.Language_valid` / `Encoding_valid` are
//! terminology-bound (deferred), and `Subject_validity` /
//! `Other_participations_valid` are `ignored`. `OBSERVATION` has no own
//! invariant.
