Hmmm. Browser manufacturers all already recognise it in the DOM (it's  
required for compatibility with e.g. screen readers that look for it).  
Adding an extension to a browser to find it is not that difficult (If I

And mine is that if it's only a should we suggest that this isn't critical  
functionality, just a nice-to-have, which is incorrect.

No, we (as argued above) imply that this is a valuable rather than  
critical feature.
