However, we had such a use case during some discussions on the WS Security list (and we actually had code in place that provided such a mechanism) but somehow the discussion showed that this usage should be avoided (can't remember the reasons for it, it's about 1 year ago). > > > > With respect to the WS Security specification I interpret the > > inclusion value "always*" or "once" without any additional > "Require*" > > assertion as "include the token as a BinarySecurityToken > and reference > > it using a Reference in the SecruityTokenReference".
