This package implements arrays, as introduced in XPath/XQuery 3.1: arrays provide a list-like data structure that (unlike sequences) allows nesting.

Arrays are immutable, so that adding a new entry to an array creates a new array.

The entries in a array are arbitrary XDM sequences.

There are functions (each supported by its own implementation class) to create a new array, to add an entry to a array, to get an entry from an array, to get the size of an array, and so on..
