WS-Security IPR question

I have a question regarding WS-Security licenses. 

I understand the WS-Security Oasis IPR statement is at http://www.oasis-open.org/committees/wss/ipr.php 

Microsoft has a license  at http://msdn.microsoft.com/webservices/docs/wss_license.asp

Do IBM and Verisign have license agreements? If so, where may I find them? 

Are the Microsoft (or other) contributors aware of any other required licenses that adopters of 
WS-Security should be aware of?

I would appreciate the correct pointers, if available. 

If no other licenses are available does that mean that only the Microsoft license is applicable? Is there a time frame for licenses to be made known, according to Oasis or other rules?

Thanks

regards, Frederick
