window object in widget and main document

Hi,
	In section 4.2 of the widget working draft, it specifies that the  
functions resizeTo, resizeBy, moveTo and moveBy should be functions  
of the window object.  A user agent may want to use only one window  
object to contain many widgets, and for this reason I believe these  
functions belong in the widget object.
	Also, in section 2.2 it specifies that the main document be  
index.html.  As noted this doesn't not allow for svg, xhtml or other  
formats.  Perhaps this could be specified in the config.xml file.

Regards,
	Brad Lassey
