    """
    Pint is a standard for International Billing from Peppol. It is based on Peppol BIS Billing 3.
    It serves as a base for per-country specialization, while keeping a standard core for data being used
    across countries. This is not meant to be used directly, but rather to be extended by country-specific modules.

    The JP PINT format is the Japanese implementation of PINT.
