 In case the validation does not complete for all source metadata (due to errors, user interruption, etc.), when the transformation is run for the same endpoint again, it will continue processing source metadata that were not processed before, hence are not included in CSV results. To re-validate an endpoint that was validated before, the CSV results file needs to be renamed or moved out of the results folder.

 #### Metadata validation and TG version classification procedure:
 1. TG version classification (1.3 vs. 2.0) is initially based on the presence of the `gmd:useLimitation` element, denoted in column *version_0* in CSV results; if the element is present, TG v. 1.3 is assumed; if the element is not present, TG v. 2.0 is assumed,
