The PARENT attribute on <container> has the declared value IDREF, which means that you need to reference an id on a "parent" element. The following will work: <unitid id="mss97">Mss 97</unitid> ... <container parent="mss97" type="folder">Folder 34</container> If you are using XSL to generate output, you would then easily be able to provide the "Mss 97" prefixed to each container text, for example, output might be Mss 97: Folder 34. I do not have time to show you the XSL at the moment, but it should not be too difficult to figure out.
