The sort key.

When an array of document nodes is sorted, the sort key is evaluated for every node in the array. Every sort key is an ordered sequence of string segment values. Furthermore, every sort key is assigned a certain position index. The position index is equal to the index of the corresponding element in the original (unsorted) array. Position indexes are used to ensure the stable sorting.
