/**
* Validate input NeTEx entities, especially relations. The validation step is mainly there to
* enable us to remove entities with “broken” references. This happens in real life, when the import
* comes from more than one source (stops register & authority transit data) and these sources are
* out of sync.
*
* Make sure the order of the validation steps are inline with the data relations. For example, if A
* reference B, any validation of the reference should be done AFTER validation steps on B. If B is
* removed, then validating A -> B, should also remove A.
