You're blurring the lines. The nested window, by definition, *cannot* be
independent of the outer window. It is a nested window, and will thus be
dependent on certain properties of the outer window(s)--as far as display is
concerned. The spec makes it clear that contained *document* should *behave*
independently of the outer document: it shouldn't inherit styles, markup
state, etc.

As I pointed out in my response to Jukka, I have a problem with this
conclusion.

This interpretation places the inclusion in a decidedly subordinate position
to the host document. I'm not convinced that this is in keeping with the
design goals of OBJECT. Consider:

host.html:
	<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN">
	<HEAD>
	<TITLE>Host Document</TITLE>
	</HEAD>
	<BODY>
	<OBJECT DATA="inclusion.html" TYPE="text/html" WIDTH="320"
	HEIGHT="240"><A HREF="http://www.w3.org">We're off to see the
	wizard!</A></OBJECT>
	</BODY>

inclusion.html:
	<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN">
	<HEAD>
	<TITLE>Included Document</TITLE>
	</HEAD>
	<BODY>
	<P><A HREF="http://www.w3.org">We're off to see the wizard!</A>
	</BODY>

Is it reasonable that these links should behave totally differently?
