      attribute<string> bag_LVC_OpenbareRuimteNaam;

      unit<uint32> bag_LVC_gerelateerdeWoonplaats
      {
         attribute<string> bag_LVC_identificatie;
      }

      attribute<string> bag_LVC_aanduidingRecordCorrectie;

container ParsedXML := parse_xml(XmlData, scheme);

unit<uint32> gerelateerdeWoonplaats := ParsedXML/bag_LVC_OpenbareRuimte/bag_LVC_gerelateerdeWoonplaats
{
   attribute<string>                 identificatie      := bag_LVC_identificatie;
