XML templates and iframe content

[rvj]

With the demise of support for RDF, does or will the XML template builder be
suitable for generating content in
XUL Iframes ?

Using the listbox example
http://developer.mozilla.org/samples/xultemp/template-guide-ex-xml1.xul
I unsuccessfully tried to use the XUL iframe element (rather than XUL
listbox element)

<iframe datasources="people.xml" ref="*" querytype="xml"
xmlns:html="blabla" >

<html:table>
<template>
................
</template>
</html:table>

</iframe>

IFrames are needed for scrolling and printing content and the template
generator seems to provide a much simpler transformation mechanism than XSL
