First version of these test files
Added test id
changed from div to section because div already maps as section
Test files created while copying over test cases from wiki
Test files submitted by Rich, Joseph, Jon between 27 June 2012 and 23 July 2012
Replaced automatated role value changes with interactive UI.

Test files for cases 567 and 568 originally automatically changed
the role, using window.setTimeout().  Replaced that with buttons
that allow the tester to control when the role change occurs, and
to reinitialize the test file.
Updates from Rich 12 Oct 2012, third try
Update from Rich changed alt text
Fixed bug in script to switch the value of aria-hidden to 'false'
when the style of the test element is set to 'display:none'.
Also, hooked theses changes up to a button to allow the tester
to make the switch at their leisure (previsou version made the
the style change automatically some time after page load).
Modified test file so that the aria-setsize and aria-posinset
values are reversed for the 'test' list item.  That is, the
author has erroneously declared the size to be 1, and the
current index to be 5.
Fixed <title> to match testable statement.
