George Stanchev commented on RAMPART-144:
-----------------------------------------

If (1) is adopted how does one create a Timestamp element that contains Created 
and Expires elements with the same value. I can foresee SP implementations that 
balk at Timestamp with Expires only and require both Created and Expires to be 
present. I think Rampart should be able to generate both Timestamps with 
Create-only and with Create==Expires.

> Timestamp with just create time element

> If we want to just have "wsu:Created" element inside "wsu:Timestamp" then 
> Rampart doesn't allow it. 
> WS-Security policy doesn't seem to define any policy semantics for above, but 
> this element is optional and often not used in practical scenarios because of 
> clock differences, but it is considered best practice to have time stamp 
> included in XMLdSig.
> I think as Created and Expires elements are not controlled by WS-Policy, we 
> could adopt for the flexible solutions as below:
> (1) In client side, if timestampTTL element in rampart-config is set to 0, 
> then wsu:expires element must not be created.
> (2) On Server side, Timestamp should be validated for full, that is if 
> Created and Expires element are present then they should be validated 
> otherwise just created time be validated. I think this is current behaviour.
