Geronimo2 uses converts the tld from a dtd based document to a schema based document.

something like this

<?xml version="1.0" encoding="UTF-8" ?>
<taglib xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-jsptaglibrary_2_1.xsd" version="2.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee">
  <tlib-version>1.0.1</tlib-version>
  <short-name>JSF Supportfor JSP Include</short-name>
  <uri>http://www.icesoft.com/icefaces&lt;/uri>
  <listener>
      <listener-class>com.icesoft.faces.util.event.servlet.ContextEventRepeater</listener-class>
  </listener>
  <tag>
    <name>include</name>
    <tag-class>com.icesoft.faces.webapp.IncludeTag</tag-class>
    <body-content>empty</body-content>
    <attribute>
      <description></description>
      <name>page</name>
      <required>true</required>
      <rtexprvalue>false</rtexprvalue>
    </attribute>
    <attribute>
      <description></description>
      <name>id</name>
      <required>false</required>
      <rtexprvalue>false</rtexprvalue>
    </attribute>
  </tag>
</taglib>

The shortname attribute is not allowed to have spaces in it according to the attribute, a validating xml editor like eclipse WTP will show the problem.
