Some functions give you an object specifier, a "reference", to an object in the app.  And you may want to know what the containment chain — the specific containment chain displayed in AppleScript — for that object is, but the object may not have a property for its container.

The object specifier knows the containment chain. That's why AppleScript can display it the way it does, e.g. word 1 of paragraph 2 of document "foo".  So AppleScript has, at runtime, its grubby little mitts on all the information he wants.  There's just no built-in function to return, say, a list of objects (e.g. {word 1 of paragraph 2 of document "foo", paragraph 2 of document "foo", document "foo", application "TextEdit"})

One could write a scripting addition that takes an object specifier and returns a list.  Would take me a couple hours.  Don't have them now.  Neither does Nebel.  But it's v. straightforward.
