The document has been around as a Working Draft for over 10 years. 
Nobody saw that problem, or thought that it was serious enough to 
comment (let alone to withdraw the document). In addition to what others 
have said, I'd also note that at a requirements stage, the main question 
is "what do we need", not "how are we best going to call it".

Regards,    Martin.
