Also, in <s:if ...> tags, you don't need to enclose the test in %{}

But remember that jsp code needs to be understandable not only to the
compiler and tags that will implement it, but also humans that will be
maintaining this code in the future. I'd suggest not saving any of
those "extra keypresses" and explicitly using the %{} wherever you
intend the expressions to be evaluated by OGNL. I would guess that
eventually more EL's will be supported by struts2, at which point this
seemingly unambiguous expression will no longer be well defined without
something specifying the appropriate EL.
