Add a "bbox" pointer events property?

Basically, this "pointer-events" property would trigger pointer events for the entire BBox area -- and could be used on graphical and non-graphical elements alike.
 
This property would allow you to clearly define when an svg-in-html tag should trigger events.
 
Something along the lines of:
pointer-events="bbox" or pointer-events="contentArea" (the latter is more generic and could be used by CSS for CSS content area if they decide to adopt SVG pointer-events)
 
where:
for svg elements, this is the DOM getBBox() area
for the base svg tag in html, would it be "ClientRectList" area from CSS?  (http://www.w3.org/TR/2009/WD-cssom-view-20090804/#the-getclientrects-and-getboundingclient)  <- note this is another integration spec uncertainty
