How to put namespace into soapenv:Body with UTL_DBWS?

Question

We are trying to make the following SOAP call from Oracle.
Outside Oracle (SoapUI v 3.6.1), the following call, generated by the tool, works:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ebp="http://www.sap.com/EBPPBillDelivery" xmlns:ebp1="http://www.sap.com/EBPPTypes">
<soapenv:Header/>
<soapenv:Body>
<ebp:BillerDataMsg>
<!--Optional:-->
<ebp1:Authorization>
<ebp1:UserName>uid</ebp1:UserName>
<ebp1:Password>pwd</ebp1:Password>
</ebp1:Authorization>
</ebp:BillerDataMsg>
</soapenv:Body>
</soapenv:Envelope>
With UTL_DBWS, I have
l_service UTL_DBWS.service;
l_call UTL_DBWS.CALL;
l_service := UTL_DBWS.create_service (
wsdl_document_location => URIFACTORY.getURI('file://appl/pc_files/spool/Wsdl/EBPPBSPServices.wsdl')
,service_name => UTL_DBWS.to_qname('http://www.sap.com/EBPPBSPServices','EBPPBSPServices')
l_call := UTL_DBWS.create_call (
service_handle => l_service
,port_name => UTL_DBWS.to_qname('http://www.sap.com/EBPPBSPServices', 'EBPPBSPServicesPort')
,operation_name => UTL_DBWS.to_qname('http://www.sap.com/EBPPBSPServices', 'getBillerData')
utl_dbws.set_property(l_call, 'OPERATION_STYLE', 'document');
utl_dbws.set_property(l_call, 'SOAPACTION_USE' , 'TRUE');
utl_dbws.set_property(l_call, 'SOAPACTION_URI', 'http://www.sap.com/EBPPBSPServices/getBillerData');
vx_xml_out := UTL_DBWS.invoke(
call_Handle => l_call
,request => XMLType('<?xml version="1.0" encoding="utf-8"?><ebp:BillerDataMsg xmlns:ebp="http://www.sap.com/EBPPBillDelivery" xmlns:ebp1="http://www.sap.com/EBPPTypes"><Authorization><UserName>uid</UserName><Password>pwd</Password></Authorization></ebp:BillerDataMsg>'));
*ORA-29532: Java call terminated by uncaught Java exception: port: {http://www.sap.com/EBPPBSPServices}EBPPBSPServicesPort does not contain operation: BillerDataMsg*
If I could manage to put namespaces xmlns:ebp="http://www.sap.com/EBPPBillDelivery" and xmlns:ebp1="http://www.sap.com/EBPPTypes" into soapenv:Envelope or soapenv:Body attributes, as I do in soapUI, it would work.
But I have found no fuhction with such functionality in UTL_DBWS.
Is using UTL_HTTP and making SOAP message manually the only way to call SAP web services? Normally, Oracle people advices to use UTI_DBWS over UTL_HTTP, but in this case it does not work.

I prefer using UTL_HTTP directly for SOAP calls - and not UTL_DBWS that IMO has a very clunky interface. SOAP is simply a XML payload over HTTP. Not that complex to do natively using UTL_HTTP.
