    """
    SI-UBL 2.0 (NLCIUS) and UBL Bis 3 are 2 different formats used in the Netherlands.
    (source: https://github.com/peppolautoriteit-nl/publications/tree/master/NLCIUS-PEPPOLBIS-Differences)
    NLCIUS defines a set of rules
    (source: https://www.softwarepakketten.nl/wiki_uitleg/60&bronw=7/Nadere_specificaties_EN_16931_1_norm_voor_de_Europese_kernfactuur.htm)
    Fortunately, some of these rules are already present in UBL Bis 3, but some are missing.

    For instance, Bis 3 states that the customizationID should be
    "urn:cen.eu:en16931:2017#compliant#urn:fdc:peppol.eu:2017:poacc:billing:3.0".
    while in NLCIUS:
    "urn:cen.eu:en16931:2017#compliant#urn:fdc:nen.nl:nlcius:v1.0".

    Bis 3 and NLCIUS are thus incompatible. Hence, the two separate formats and the additional rules in this file.

    The trick is to understand which rules are only NLCIUS specific and which are applied to the Bis 3 format.
