your approach sounds reasonable to me. We may think about implementing
this "unknown issue" as a fundamental railML 3 pattern.
That is a good idea. It should probably be discussed broader than just in this thread.

whenever an optional attribute (or optional element) is not provided,
this means that the related information is unknown.
Unless a default value is specified. We should strive to always define a default value for optional attributes when possible. A lot of attributes will still not have a meaningful default, in which case a rule interpreting them as unknown will be useful.
