Send two or more parameters to OSLC-DXL Services

Hello,

 
I use the OSLC-DXL Services to execute some functionality no supported by OSLC. I test these services using a DXL script whose function has 2 input parameters. I follow the instructions given on IBM Knowledge Center, providing the two parameters separated by commas (","), but the service returns "dxlServiceResult: uninitialised".
 
I test with only one parameter, and it works.
 
The content that I send is:

<?xml version="1.0" encoding="UTF-8"?>
<rdf:RDF

  <doors:Arguments>
  <doors:arguments>FistParam,SecondParam</doors:arguments>
  </doors:Arguments>
</rdf:RDF>
       
Thanks for your help
