WCF Message contract namespace problem

Hi all, I have a WCF service and I have tags like

 
   -- Some Data Here --
 
 
   -- Some Data Here --
 


And I tested my service in SoapUI, but it is showing contracts with some extension as:


 
   -- Some Data Here --
 
 
   -- Some Data Here --
 


But I want my contracts appear as they are in contracts.
If somebody can give the solution, Thanks in advance.

I am using [MessageContract]
