Sorry, I don't have an exact link to the description
of AppleScript's Finder Object Model. I'm sure it's
buried somewhere on the AppleScript site.
 
What I use is Script Debugger 3.0's Object model view
in it's Application Dictionary to view such things. It
presents a graphical view of an app's dictionary, that
is if the app supports the object model (like the
Finder). A trial version is available for download.

Not sure if this would be of interest but to find out
more about AppleScript's language implementation
there's also Apple's Developer section:
http://developer.apple.com/techpubs/macosx/Carbon/interapplicationcomm/AppleScript/applescript.html
http://www.apple.com/applescript/developers/
http://www.apple.com/applescript/resources/

I agree with your other points but I'm not quite sure
about this one regarding the name of this desired
class.

Although, I'm not sure what a good name might be
Filename sounds, to my ears at least, too much like
simply a class without any further responsibilities
other than naming. It seems to me that an object which
might also be responsible for such things like moving
or copying speaks out for an name which sounds more
like an entity rather than a label or id. 

But that may be due to my prior experience in
AppleScript where a file's name is just a property of
a file object. e.g.-

tell application "Finder"
	name of file x
end tell

Just a thought,

Anthony
