How to have dynamic parameters with nonstandard taglib with JSTL

Question

Hello, I am using webwork 2.2.7, tomcat 4.1 (I have a java 1.4 requirement unfortunately), and jakarta-taglibs-standard-1.0.6 and some nonstandard taglibs and need to pass dynamic parameters to the nonstandard taglibs.
I can see that the standard taglibs handle the ${foo} syntax for attributes but the nonstandard taglib is just getting set with "${foo}". I really need to set attributes of the nonstandard taglib with dynamic parameters. Is there some combination of c:set and the <%= syntax that can work?
I have tried the following which does not work:
<input:selectBox options="${accounts}"/> <!-- the nonstandard taglib just has the options property set as the literal string "${accounts}" -->
I was thinking something like the following might work but it doesn't
<c:set var="accounts" value="${accounts}"/> <!-- the core taglibs can deal with ${accounts} appropriately -->
<input:selectBox options="<%=accounts=%>"/>
I don't care how but I need to somehow access ${accounts} and set that Collection as an attribute of the taglib. Can anyone please help me solve this problem? Thank you very much.
