It seems like the the real question is whether pointer-events should inherit if not explicitly told to?
Here goes:
<g pointer-events="none">
    <rect x="20" y="20" width="200" height="200" pointer-events="auto" />
1. According to CSS: http://www.w3.org/TR/CSS2/syndata.html#illegalvalues 
pointer-events="auto" will be ignored as though it doesn't exist.
2. Result:
<g pointer-events="none">
    <rect x="20" y="20" width="200" height="200" />
3. Question: what pointer-events property does rect take on?  inherit "none"? or use default "visiblePainted"?
4. So I guess your real question is whether pointer-events should be inherited even if not explicitly declared to "inherit"... or if they should be "visiblePainted" instead?  Would that sum it up better?
Someone else should be able to answer that ... as I'm not 100% sure.

Subject: pointer-events test case


Here is a test case for some interactions with the pointer-events property

This test case show how implementation handled the pointer-events property when an element is nested in another element with a different pointer-events property value.

At that point, my test show that Opera has a problem when an element with an invalid pointer-events' value is wrap by an element with the pointer-events' value 'none'. According to the CSS 2 specification, Opera should ignore the invalid value and therefore use the default value for pointer-events which is "visiblePainted". It seams that Opera act like the pointer-events' value were "inherit" and does not fire pointer events on the child element.

Firefox and Chrome handle it that way.

Could someone explain to me how is it possible to turn that test case into a formal test case for the SVG spec?
