from lxml.builder import ElementMaker

...

        nsmap = {
            None: 'urn:oasis:names:specification:ubl:schema:xsd:' + doc_name,
            'cac': 'urn:oasis:names:specification:ubl:'
                   'schema:xsd:CommonAggregateComponents-2',
            'cbc': 'urn:oasis:names:specification:ubl:schema:xsd:'
                   'CommonBasicComponents-2',
            }
        em = {
            'cac': ElementMaker(namespace=nsmap['cac'], nsmap=nsmap),
            'cbc': ElementMaker(namespace=nsmap['cbc'], nsmap=nsmap),
            }

        ...
        addresses = [

        locations = [
            em['cac'].PyhtiscalLocation('foo'), 
            em['cac'].PyhtiscalLocation('bar')
        ]
        em['cac'].PartyTaxScheme(
            em['cbc'].RegistrationName(registration_name),
            em['cbc'].CompanyID(commercial_partner.sanitized_vat, schemeID='11'),
            *addresses,
            *locations
        )
        ...
