Hi

Can you tell me if there is a work-around for the unsupported

Lang=en identifier in the header

I tried putting  <html lang="en" xmlns="http://www.w3.org/1999/xhtml">
But that failed.

I want to make the page compatible with 
Bobby accessibility program

http://bobby.watchfire.com/bobby/html/en/index.jsp

I have left the test page at 

http://www.macsvision.co.uk/test.html if you want to cast an eye

over it

regards

Bryan Archer
