preparent element-qualifier* (is | isnt) namespace-modifier? (element-name | element-name-list)

A test that checks to see whether a specified element has a preparent (ancestor of a parent) with a given element-name. In other words, it answers the question: Is the given preparent an ancestor of the specified element?
