Aggregate of every generated DATEX II model version. Depending on this artifact pulls in all datex4j-model-vX_Y modules (v2.0 through v2.3 and v3.0 through v3.7) transitively, together with their bundled XSD resources and ServiceLoader-registered DatexModelProvider implementations. Consumers that only need a single version may depend on the matching datex4j-model-vX_Y module directly instead.
