I've been trying to catalog all of the cases where OGNL exists and where it can be replaced.
Since different ELs specify different mechanisms to state "this is an expression to be evaluated", I wonder what we should do about the delineating characters "%{"/"}" vs. "${"/"}" vs. "#{"/"}", etc.
Right now in result specifications in struts.xml (when the result supports it, and when parsed) we use ${} to say "this is an expression to be evaluated" even though it's currently ognl (which uses %{}). I'm of several thoughts regarding this. One one hand since it's OGNL I think it should be %{}. On the other hand if we're contemplating switching ELs maybe it should not be EL-specific so that the EL can be changed without modifying all the expressions.
So: Is it possible to have these change with the EL? Is it desirable? If we want to use a single type for all ELs, which should it be?
