I propose that we also can have a "position-stack"
property with the following values :

    - [initial] "auto" : A new local stacking context is
    created as the rules are defined in CSS 2.1/3.0
    (computed to "create-new" if a new stacking context is
    needed, to "keep-old" otherwhise).

    - "create-new" : A new local stacking context is created
    anytime (top/left/right/bottom of children now refer
    to positions relatives to the element, even if these
    element is not a float or absolutely positionned

    - "keep-old" : No new stacking context is created even
    if the element is absolutely positionned or floated
    (top/left/right/bottom of children now refer to
    positions relatives to the nearest stacking context).

<div style="position-stack: create-new; margin: 10px; width: 110px; height: 
20px; background: blue">
    <div style="position: absolute; top: 5px; left: 5px; width: 100px; 
height: 10px; background: white;"></div>
