Bespin is in fact not valid HTML5, but for another reason. HTML5 says:  
"When authors use the canvas element, they must also provide content  
that, when presented to the user, conveys essentially the same  
function or purpose as the bitmap canvas." Thus, Bespin is  
nonconforming because it fails to provide fallback that conveys the  
same function.
