Alright, I agree, I don't have a problem with it. But is it possible to  
create a detailed documentation for this, including "How do I code it  
right?," with wrong good and examples? In my opinion, if there was a good,  
clear and understandable (for human regular beings that is) documentantion  
which developers could refer to, and if it succeeded in getting known  
widely, it could improve the overall knowledge and accessibility. It  
reminds of the longdesc attribute - it's useful but nobody really knows  
how to make it right.
