Both correct.

There's some general (quite likely at least partially outdated) vc 
documentation at 
http://www.xemacs.org/Documentation/beta/html/xemacs_17.html#SEC148 .  The 
GNU Emacs documentation on it might be closer to what we have now:
http://www.gnu.org/software/emacs/manual/html_node/emacs/Version-Control.html

However, at least the XEmacs doc above doesn't seem to cover how to 
auto-activate vc when opening files under control of supported version 
control systems ("backends").  The way I've always done it is this in my 
~/.xemacs/init.el:

(require 'vc-hooks)

Dunno where that came from, it's been there for ages, probably longer than 
I've even understood what it means.
