Another 'best' practices question ??

[William Case]

Hi;

I have downloaded nxhtml-1.00.070501.zip.  I now have to put it
somewhere and then add it to my loadpath.  Is that correct?

If so, where should I put it?  I am looking for a best practises answer
that would be applicable to other downloaded or created *.el files.

I have a half answer from the emacswiki, but that leaves me with
choosing the location and as a relative newbie it is not clear what
would be the best choice.

I have emacs 22, on a Fedora core 6 machine.  My existing loadpath is:

("/usr/share/emacs/22.0.95/site-lisp" 
"/usr/share/emacs/site-lisp" 
"/usr/share/emacs/site-lisp/site-start.d" 
"/usr/share/emacs/22.0.95/lisp" 
"/usr/share/emacs/22.0.95/lisp/url" 
"/usr/share/emacs/22.0.95/lisp/textmodes" 
"/usr/share/emacs/22.0.95/lisp/progmodes" 
"/usr/share/emacs/22.0.95/lisp/play" 
"/usr/share/emacs/22.0.95/lisp/obsolete" 
"/usr/share/emacs/22.0.95/lisp/net" 
"/usr/share/emacs/22.0.95/lisp/mh-e" 
"/usr/share/emacs/22.0.95/lisp/mail" 
"/usr/share/emacs/22.0.95/lisp/language" 
"/usr/share/emacs/22.0.95/lisp/international" 
"/usr/share/emacs/22.0.95/lisp/gnus" 
"/usr/share/emacs/22.0.95/lisp/eshell" 
"/usr/share/emacs/22.0.95/lisp/erc" 
"/usr/share/emacs/22.0.95/lisp/emulation" 
"/usr/share/emacs/22.0.95/lisp/emacs-lisp" 
"/usr/share/emacs/22.0.95/lisp/calendar" 
"/usr/share/emacs/22.0.95/lisp/calc" 
"/usr/share/emacs/22.0.95/leim")

Should I create a new directory in "/usr/share/emacs/22.0.95/lisp" or
add the file to an existing directory?  I tried to include it with the
XHTML-mode but I could find specific XHTML, HTML or PHP mode files or
directories to include it with.  Is that a good idea or not?
