Sorry to disappoint you there, but the XML standard does not force
siblings to be entered in a specific order. As such, there is no XML
parser which will guarantee you that xml-nodes are returned in the
order they come up in the file. And they do not have too, it is not
part of XML-spec itself.
As a consequence of this, it is impossible for FrapMenu (or any other
application which uses XML) to preserve the order since it is not even
certain that the order in which the nodes are presented to him is the
order in which they where inside the file.
On a side-node, usually it does work this way, but we cannot rely on this.
