public class WithPedigree
extends SystemFunction

The saxon:with-pedigree function, new in Saxon 9.9.

The function is applied to a map or array, and it returns a map or array, with the same content, but with a different implementation such that all downward selections from the map/array to contained maps and arrays maintain information about the selection route, which can be used to get information about the containing maps and arrays in a JSON-like tree.
