Collapsible regions in HTML (from an XSLT transform)

There was an error in the manner in which Brooks code was creating collapsible regions within HTML.  This may apply to more than one project, but manifested for sure in the Telvent.SE.FiberCustomerReport.  The cause of the error was in the Javascript code which essentially hid ALL of the rows.  You don't want to do that, because if you do, then you won't be able to click on a row to get the region to reappear.  I have a nice working example here.
