Good question. I don't have solution for that. In case of wsdl2xforms we 
submit the instance to web service and never retrieve it.

Would xsi:nil attribute give you the same result? Something like this:

<xf:instance>
  <root>
    <format xsi:nil="false">xml</format>
  </root>
</xf:instance>
<xf:bind nodeset="/root/format/@xsi:nil" calculate=".. = ''"/>

If I'm correct, Chiba even sets xsi:nil automatically for you, if you 
happen to have that attribute.

I understand, that this not exactly "missing element" feature that you 
needed, but maybe the target application handles the missing element and 
xsi:nil="true" element the same way?
