In JSF1.2, the newly specified "unified EL" will be supported anywhere
in the page.
This means that you will be able to keep on using JSP style EL
statements - those will be immediately executed on building the page,
and the JSF style EL statements (in the unified EL called "deferred"
EL statements) will be passed on to the JSF subsystem.

Martin
