Recursive Form

I'm working about the faisability study to translate ICS forms (defnned by ETSI) as XForms.
My first question is : how to create recurive formes?
As an exemple, I supose the model attached to my representation is somethig like
 
...
<paragraph id="id1" title="Title1">
    <paragraph "id="id11" title ="paragrah 1.1">
    <table>
        <tablecontent id="t1" title="Table to be filled in">
         ... many fiield to fill in ...
        </tablecontent>
   </table>
   <paragraph id="level3" title="paragraph 3th level>
        <table id="t2 title="to be filled in 2"> ...</table> 
        <table id="t3 title="to be filled in 2"> ...</table>
  </paragraph>
</paragraph.>
</paragraph>
 
I need to create a Form to recursivly generate the hierarchy of paragraphs and , of course, the tables...
I don't know the exact deep of this tree...
I try using <xforms:repeat > and <xforms:index> but at this time, I can't obtain a correct result.
 
Cane everyone help me?
 
Thanks
