But this is in the YANG source; I think Ian asked about the tree
diagram syntax. Maybe the corresponding syntax in the tree diagram
could be simply:
augment /nat:nat/nat:instances/nat:instance
/nat:mapping-table/nat:mapping-entry:
Or even simpler, maybe we can say that any string in the tree diagram
syntax can follow the YANG string rules.
