The Unified EL does not currently support he ability to pass parameters to
methods. For example:
is not possible. This feature is available extensions, such as the JBoss EL
It's also available in OGNL, which is used by other web frameworks.
Sine there are no plans for an update to the Unified EL in the 2008 time frame,
I propose we extend the EL (as JBoss has done) to support this feature.
