two fixes in here:

* when i moved the liink to "expand all -- all sections" to the top of the document, the parameter needed to change to find all the content to be expanded.  prior to this fix, it had "broken" since it wasn't finding any nodes to expand.  [it had worked ok when the link was right above the first section table]

* the expand all functionality now works in IE9+.  I'm using the javascript xpath library wgxpath (http://code.google.com/p/wicked-good-xpath/).
