/**
* A DOM-specific {@link XMLValidateContext}. This class contains additional
* methods to specify the location in a DOM tree where an {@link XMLSignature}
* is to be unmarshalled and validated from.
*
* Note that the behavior of an unmarshalled XMLSignature
* is undefined if the contents of the underlying DOM tree are modified by the
* caller after the XMLSignature is created.
*
*
Also, note that DOMValidateContext instances can contain
* information and state specific to the XML signature structure it is
* used with. The results are unpredictable if a
* DOMValidateContext is used with different signature structures
* (for example, you should not use the same DOMValidateContext
* instance to validate two different {@link XMLSignature} objects).
