Description

The trigger is this OmniFaces issue: http://code.google.com/p/omnifaces/issues/detail?id=9

OmniFaces has a <description> element right before <namespace> element in the taglib.xml files which describes the taglib.

<facelet-taglib id="o"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facelettaglibrary_2_0.xsd"
version="2.0"
>
<description>OmniFaces UI components.</description>
<namespace>http://omnifaces.org/ui</namespace>

...
</facelet-taglib>

It get parsed fine on Mojarra, but on MyFaces 2.1.7 the following exception occurs:

Caused by: org.xml.sax.SAXException: Error Handling [jar:file:/C:/Users/BalusC/Documents/Work/M4N/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp2/wtpwebapps/omnifaces_test/WEB-INF/lib/omnifaces.jar!/META-INF/omnifaces-ui.taglib.xml@20,33] <description>

Removing the <description> element solves the problem. But this is not what we want. Putting the <description> element after the <namespace> element also solves the problem, but Eclipse marks the XML invalid according the XSD.
