The '%' tells Struts to parse it with OGNL. OGNL is a very powerful
expression language used by the core of Struts 2. It supports
advanced features like method calls, projection, and data conversion.

I've noticed that there's an EL-like syntax used within some tags in
the sample jsp's that ship with the Struts 2 apps. Namely:
<s:a href="%{url}">
How does the percent sign work in the line above? When I use ${url}
it works just as well.
Am I just behind on Expression Language specs? or is this a
convention that I'm unaware of in the new Struts 2 tags?
Thanks for getting me up to speed!
