Hi,

We have two JSP documents a.jsp and b.jsp. Suppose that some custom library is
defined correctly under the prefix "x". There is a tag library validator
associated with the TLD. The same bug is observed in Tomcat 5 while it is
working on Tomcat 4.
---- a.jsp -----
<?xml version="1.0" encoding="UTF-8"?>
<jsp:root version="2.0" xmlns:jsp="http://java.sun.com/JSP/Page"
xmlns:x="http://some/tld" >
  <jsp:directive.include file="b.jsp"/>
</jsp:root>

---- b.jsp ----
<?xml version="1.0" encoding="UTF-8"?>
<jsp:root version="2.0" xmlns:jsp="http://java.sun.com/JSP/Page"  >
    <x:doAction/>
</jsp:root>

When I try to request a.jsp i receive this exception:
org.apache.jasper.JasperException: b.jsp(%row%,%column%) The prefix "x" for
element "x:doAction" is not bound.

But when I add the namespace to the jsp:root of the b.jsp the validator of the
taglibrary complains with:

Validation error messages from TagLibraryValidator for trx
null: org.xml.sax.SAXParseException: Attribute "x" bound to namespace
"http://www.w3.org/2000/xmlns/" was already specified for element "jsp:root".

This is against JSP 2.0, 2.1 specification: JSP.10.3.5 Collective Application of
Inclusion Semantics. This makes inclusion of JSP documents with custom tag
libraries that validate the XML view impossible.
