#141 Unable to override roleName of included node

[Ken Webb]

An included file may be used multiple times in an application. It may take on a different role each use. Therefore it should be possible to override the roleName of the top-level element in the included file.

For example, a CompositeStructure.xml file might have 2 identical adjacent xi:include tags. To distinguish these, the first one could have roleName="one" and second roleName="two".
