> In VolcanoRuleCall#matchRecurse, when a node's parents are found, it is necessary to check the child is in the right position (ordinal) of the parent's child list. 
> However, when the child policy is UNORDERED, the constraint should be relaxed, as the child can be in any position of the parent's child list.
