foreign namespace in SOAP responce

Hi, All

I'm using 4js webservice application as client to some .NET server.

received soap responce have following structure:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <soap:Body>
    <UpdateAvailResponse xmlns="http://www.reconline.com/">
      <UpdateAvailResult>
        <xs:schema id="NewDataSet" xmlns=""
        xmlns:xs="http://www.w3.org/2001/XMLSchema"
        xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
          <xs:element name="NewDataSet" msdata:IsDataSet="true"
          msdata:Locale="de-CH">
            <xs:complexType>
              <xs:choice maxOccurs="unbounded" />
            </xs:complexType>
          </xs:element>
        </xs:schema>
        <diffgr:diffgram
        xmlns:msdata="urn:schemas-microsoft-com:xml-msdata"
        xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1" />
      </UpdateAvailResult>
    </UpdateAvailResponse>
  </soap:Body>
</soap:Envelope>

is there some possibility for client to ignore xs:schema and diffgr:diffgram 
elements ?
now client stops with "Message decoding failed" fault
