It was also a real bugger to have to work out that the array containing styles should contain 'Styles' and not 'Style' as per WA supplied!
array( 'Style','FontFormat','FontName','FontSize'),
That from a fresh download.
Why can't WA update the downloadables when errors are reported? Just a thought. Not disputing that time spent making validation tooltips wasn't time well-spent, but it's nice to get the engine running before you fiddle with the indicators.
