Sub-root-objects

The XML element for the sub-root-objects is named sub_roots. It contains for each sub-root-object an XML element named sub_root. The element sub_root has the attribute identifier, which specifies the identifier of the sub-root-object (it is an integer). The element sub_root also contains the corresponding root-object, as described in this section 22.2.

      <\root>
   </sub_root>
   <sub_root identifier="3">
      <root>
          ...
      <\root>
   </sub_root>
