Adding WSS Headers to the WSDL

[Steve Karlovitz]

I was wondering if somebody could help, I have written a web-service  
that is to be consumed by SalesForce.com.  The web service utilizes WS- 
Security, I have been told that in order for SalesForce.com to consume  
and utilize this web-service I have to add the WSS definition to the  
WSDL.  Does anyone have  a working example of this?  I am using  
username/pass and timestamp tokens.

Thanks
Steve
