I have recently been asked by a couple of companies whether the
correct form of address is "X11" or "X.11".  My response is that
I like "X Window System" and "X" (and I don't particularly like
"X Windows"), and I like "X Version 11", but if you want to get
both "X" and "11" into the same word, I like "X11".

"X Window System" is a trademark of MIT.
