We don't need a new one: we have one already. The advantage of passing
an object is that it's easier for parsers to provide richer error
information (by subclassing XmlException).

Because the spec says:

* <p>This map will be valid only during the invocation of the
* <code>startElement</code> callback: if you need to use attribute
* information elsewhere, you will need to make your own copies.</p>

If it doesn't implement cloneable, how do you make your own copy?
