JSP 2.0 tag file latest syntax doesn't work in JBoss 4.0

Here is an example tag file:

<%@ attribute name="greeting" required="true" %>
<%@ attribute name="name" required="true" %>
<h2><font color="black">${greeting}, ${name}!</font></h2>

I try to use the tag in a simple page, such as:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<%@ taglib prefix="tags" tagdir="/WEB-INF/tags" %>


<html>
 <head><title>Tag Files Example</title></head>
 <body>
 <h1>Tage Files Example</h1>
 <tags:test2 greeting="Hello" name="Craig"/>
 </body>
</html>

Deploys to JBoss 4.0.1 OK, but when accessing the above page it gets:

java.lang.RuntimeException: org.apache.jasper.JasperException: /WEB-INF/tags/test2.tagx(1,2) The markup in the document preceding the root element must be well-formed.

====================
However, older style tag files do work OK, such as the following:

<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.0">
 <jsp:directive.attribute name="a"
 type="java.lang.String"
 required="true"/>
 <jsp:directive.attribute name="b"
 type="java.lang.String"
 required="true"/>

 <jsp:text>A sample link: <a href="${a}"> ${b} </a></jsp:text>
</jsp:root>

Does JBoss 4.0.1/Tomcat support the newer syntax? Do I need to configure something special to enable that syntax?
