I have a WebService API which needs 2 of its parameters to be optional in the WSDL
public wsProxy[] Insert(wsProxy[] proxies, string loginname, string password, bool returnNewData)
{
  //code here
}
I need to a way to show loginname and password as optional in the WSDL.
Is there any way to do this in C#.  Can I maybe add an tag in front of the parameters like this [optional]loginname? 
I have been looking around but haven't been able to find anything so far.
