# purpose:  Validate electronic invoices in XML format that are intended
#           to be compliant with European norm EN 16931 and, potentially,
#           also with a specific Core Invoice Usage Specification (CIUS),
#           which is German XRechnung standard in the context of this
#           software. For the validation and validation configuration, this
#           script employs the reference implementation of German government
#           body KoSIT, which is also responsible for the specification of
#           the standard XRechnung.
