Overview

Post-parse semantic validator, checking a parsed archetype against the VARID..VDFPT rules (Beale07, p.100). VARID/VARDF/ VARON/VDFAI are already enforced structurally by the RM/AM object model itself (their setters raise on construction), so they can never actually fail here - they're still checked explicitly, both for rule-traceability and so a validator run against a duck-typed object (not necessarily a real OpenEHR::AM::Archetype::Archetype) stays honest.

end

#validate_instance(rm_root) ⇒ Object

Checks rm_root against the archetype's definition, returning a path-annotated OpenEHR::Parser::Exception::Validation:: InstanceNonConformant for the first violation found (path resolved via rm_root.path_of_item, the PATHABLE navigation method), or [] when rm_root fully conforms.
