Sorry for the delay on getting back, we have been really busy at the winery for the last couple of weeks. We have a choice between using our own name and referencing the type or reusing the same name and type from the WS Trust specification. Which is chosen is going to be just a question of style and a question of what that referenced specification looks as being a top level element. However in this case, there are differences between what is specified in this document and what is specified for wst:RequestedSecurityToken, specifically the addition of the tokenType parameter. We could alternatively defined this as <eps:WSToken> <wst:RequestedSecurityToken/> <wst:TokenType> </eps:WSToken> I would not object to doing the change to the latter structure, but it is not a direct mapping currently.
