Or a motivation for enhancements to the EL in some future version of JSP
(the EL in JSTL 1.0 is being formally adopted into JSP 2.0, so you can use
it everywhere in a JSP page, and any future enhancements will happen in
versions of JSP > 2.0).

Personally, I'd suggest not trying to support "partial references" in the
struts-el library similar to what the nested taglib can do. We would have
to define the semantics of this ourselves, which is unlikely to be
compatible with whatever does finally happen on the standardization front.
