What you would like to do is to be able to use template "parameters"
in logic tags.
I have another solution to this problem : add a tag importing template
"parameter/attribute" in jsp scope (page, request, ...), as a bean.
Like this, you can use logic tag with the imported bean (which in
reality is a simple String).
<!-- import template attribute in the specified scope -->
<template:importAttribute name="chapter" scope="page" />
<!-- Do what you want with the bean -->
<logic:present name="chapter">
...
</logic:present>
Advantages of this approach :
* No need to modify existing logic tags
* No template stuff in struts core library : Struts and templates
still well separated
* Imported bean value can be used in any others tags accepting a bean
This proposed solution already exist in Components / Extended Templates.
So, you can test it immediately ...
