4  * A Receiver that can be inserted into an event pipeline to copy location information.
5  * The class acts as a LocationProvider, so it supports getSystemId() and getLineNumber() methods;
6  * the location returned can vary for each node, and is set by the class generating the events.
7  * The class is used when it is necessary to copy a subtree along with its location information;
8  * for example, when copying an inline schema within a stylesheet to a separate schema document.
