your approach sounds reasonable to me. We may think about implementing
this "unknown issue" as a fundamental railML 3 pattern. This means:
whenever an optional attribute (or optional element) is not provided,
this means that the related information is unknown.
Any comments from the community are highly appreciated.
Best regards
