edifact-mapper 0.19.0

//! A condition naming one group instance ("in dieser SG8", "in diesem CCI")
//! judges a nested-list element by its own instance, not by any in the message.
//!
//! Reported by mako-twin against 0.17.0 (UTILMD Strom 55043): each element
//! alone raised nothing, and the same element beside another group raised a
//! finding. The inputs are the entity maps their gate passed (synthetic data):
//! `*__clean` is the element alone, `*__fp` the element beside the other group,
//! `rundlauf_*` a full round trip.
