Duplicating a DOMDocument?

Is this the best way to duplicate a DOMDocument?

DOMNode* n = original->cloneNode(true);
DOMDocument *copy = static_cast<DOMDocument *>(n);

Is there a way of doing this that avoids using a static_cast?

Yes.

No, there isn't.  In C++, cloneNode() could use a co-variant return 
type, but the DOM interfaces are designed to be implementable by a wide 
range of languages.
