SOAP Service call Issue

Hello,

I am currently trying to make SOAP call to Oracle Right Now(ORN) Enterprise. ORN provides WSDL however I was not able to connect to the WSDL via Web Service smart node, getting 'An error occurred while processing the WSDL. It may not be a valid WSDL 1.1 document. (APNX-1-4041-002)'. tried with third party SOAP test tool and it worked. I am guessing the WSDL is currently not supported by Appian.

Is there an another way to make SOAP call other than Web service smart node?

I was looking into 'Send HTTP Request Plug-in' plug in. The plug in description says it supports to send SOAP XML to a Web Service but didn't provide further instructions. 

If someone can provide more high level details implementation direction or any other approach that I can try, I would really appreciated.

FYI, the following is the example SOAP XML provided ORN for the operation I want to use.
