I am no expert, but here is my guess:  When new document is loaded into
a window, tab or frame, all the handlers for that window/tab/frame are
reset to those of the new document (because it makes sense and to
prevent XSS issues).  Thus when your file is loaded into the IFRAME, the
load handler for that IFRAME is set to the load handler (possibly none)
specified in that file.

Thus to make your outer document react to completion of loading content
in your IFRAME, you will have to rely on something that does not belong
to the document in that IFRAME, OR put code in the file you are going to
load.

Another option would be to load the document with XMLHTTPRequest.
