Re: Nested Tags Question

For JSP 1.2 and earlier, <rtexprvalue> means an attribute can take an expression
of the form <%= ... %> as its value. It's not until JSP 2.0 that the container
provides the same level of built-in support for EL expressions. If you want to
use EL expressions for attribute values in your own tags you have to handle it
yourself and set <rtexprvalue> to false. See the following for an example:
