All Known Implementing Classes:

DescendantNodeJoinConditionImpl
```
public interface DescendantNodeJoinCondition
extends JoinCondition
```
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.
