Detailed Description

A helper class for validating identity constraints.

This class represents a target or qualified node from the target or qualified node set as defined in the validation rules at http://www.w3.org/TR/xmlschema11-1/#d0e32243.

A target node is part of the qualified node set, if all of its fields are not empty.
