A NodeSetExpression that retrieves nodes in order according to a specified sort key.
Note there is no direct XSL expression syntax that generates this.
The expression sorts a base NodeSet according to the value of a specified
sort key. The sort key may be composite. The base NodeSet will always be in document
order.

according to the number of sort keys defined when the SortedSelection was
