Mathew, this is exactly what I want!!!

So you think this is possible?
okay, we will try again check all XDK docs and examples.

What difference?

I think you already have read my answer that YES,
    Macromedia XDK allow us to have several logical Xtras
    inside of single file Xtra which we all install into Director

Right.

In REALbasic, developers drop into folder "plugins" just one file "V4RB".
Inside of this plugin are hidden many classes.

I think we confuse here

    Xtra -> file that is installed into Director
    Xtra -> some ala-class which we can instantiate in Lingo
            and call its handlers

I also think...may be use scripts as wrappers.
Something similar we have made in Valentina PHP.
