  | RefResolution
    -- ^ Indicates a reference that failed to resolve.
    --
    -- NOTE: The language agnostic test suite doesn't specify if this should
    -- cause a validation error or should allow data to pass. We choose to
    -- return a validation error.
    --
    -- Also note that ideally we would enforce in the type system that any
    -- failing references be dealt with before valididation. Then this could
    -- be removed entirely.
