As general rule, do we need more than one way to define the same thing?  You seem to ask the same question implicitly below.

> There is no mention of nor need to define "decade". In fact, 19xx - depending on whether we decide that x can replace two digits, not necessarily just one -- would mean the same thing as 1900/1999. So the x notation serves as a shorthand. I personally can't see why it's necessary but Ed says he needs it.
