* If a sequence of nodes is needed, the node contained in the
* DOMStructure is the first node of the sequence and successive
* nodes can be accessed by invoking {@link Node#getNextSibling}.
*
*
If the owner document of the DOMStructure is different than
* the target document of an XMLSignature, the
* {@link XMLSignature#sign(XMLSignContext)} method imports the node into the
* target document before generating the signature.
