iframe template content into htnl document

As far as I understand it, the template generator creates elements within 
the XUL DOM

Even though its possible to create HTML elements,  these are within the XUL 
dom and therefore the
content cannot be printed

would it be possible for template builder to recognise wether the containing 
element is an IFRAME element
and build an html document which can then be printed ?


    <iframe   datasources="people.xml" ref="*" querytype="xml">

            <template>

              //  html elements

           </template>

  </iframe>

It appears that all the hard work has been done!!!
