public class SerializableLocatorImpl extends Object implements Locator, Serializable
It isn't clear whether subclassing LocatorImpl and adding serialization methods makes more sense than copying it and just adding Serializable to its interface. Since it's so simple, I've taken the latter approach for now.

public SerializableLocatorImpl()
SAX says "This will not normally be useful, since the main purpose of this class is to make a snapshot of an existing Locator." In fact, it _is_ sometimes useful when you want to construct a new Locator pointing to a specific location... which, after all, is why the setter methods are provided.
public SerializableLocatorImpl(Locator locator)
Create a persistent copy of the current state of a locator. When the original locator changes, this copy will still keep the original values (and it can be used outside the scope of DocumentHandler methods).
