I presume what you want instead is that element-rooted queries are
handled by matching such that each simple selector (CSS2 definition)
or sequence of simple selectors (css3-selectors definition, and I
*still* object to changing the meaning of existing terms) must match
an element that is or is a descendant of the specified element (the
root of the query).

Or do you want to eliminate "is or" in my previous paragraph, to
exclude the query root?  Or something else?
