There is no such thing as a "W3C Standard" or a "W3C Standards Track".  (You 
are confusing that with the IETF.)  With the W3C, all specifications that 
are not yet Recommendations could be said to be "on the standards track" as 
all such documents "may be updated, replaced or obsoleted by other documents 
at any time."

It has been used production environments before, though.  The problem here 
appears to be instead, as always, invalid markup, in combination with not 
handling host objects properly.  That is what usually happens with copy & 
paste without common sense and basic clueness, particularly in this field.  
When you look at this junk code more carefully, it is a miracle that it 
works as posted, assuming that it does.
