Attempting to work with author mode, CSS, and ANT. It only works if the ANT file isn't prefixed by "build" (i.e. not associated with ANT in oXygen) and you have to work around the lack of flexibility in the ANT's XML. You can more or less force it by putting an @el='blah' on the description element; you don't get hierarchical XML, but it might be enough for a simple ANT file with some documentation.
