What about also use xmlns ?

<?xml version="1.0" encoding="UTF-8"?>
<jnlp xmlns="http://ns.jcp.org/spec/javawebstart"  codebase="http://www.mysite.com/app">
<information>
<title>Draw!</title>
<vendor>My Web Company</vendor>
<icon href="draw-icon.jpg"/>
<offline-allowed/>
</information>
<resources>
<j2se version="1.3+"/>
<jar href="draw.jar"/>
</resources>
<application-desc main-class="com.mysite.Draw"/>
</jnlp>

So, we would have a clean NS identifier...
