iteration-level()
If a target structure node is iterated several times due to its path, this function can be used (on the node itself or on fields or nodes below it) to display the current iteration level. Note: The iteration level is also incremented if a node was not entered (→ "Effect of functions on target structure nodes") in an iteration.
Example
Node "iteration" was iterated four times due to its path. But the node was not entered during the second iteration. The field "iteration_level" contains the function.
