How to import UBL 2.0 XML schema

We would like to generate UBL 2.0 XML files and downloaded the XSD files from When I import the XSD file Invoice.XSD into Mendix I get the following error: Error: "The namespace attribute 'urn:oasis:names:specification:ubl:schema:xsd:QualifiedDataTypes-2' of an import should be the same value as the targetNamespace 'urn:oasis:names:specification:ubl:schema:xsd:QualifiedDatatypes-2' of the imported schema. Is there a way to get around this error?
