Package: Default

Tests whether the descendantSelector node is a descendant of the ancestorSelector node.

A node-tuple satisfies the constraint only if:

$descendantSelectorNode->getAncestor($n)->isSame($ancestorSelectorNode) && $descendantSelectorNode->getDepth() > $n

would return true some some non-negative integer $n, where $descendantSelectorNode is the node for descendantSelector and $ancestorSelectorNode is the node for ancestorSelector.
