Good question, Lee. The EL doesn't support this, primarily (in my
opinion) because we didn't think that nonprogramming page authors would
need a feature like this. Adding a feature to a language means that all
users -- not just the advanced ones -- will have to understand it to be
able to maintain pages written by other users.
Have you run into a practical situation where this kind of indirection is
absolutely necessary?
