The XML ID for the XML digital signature.
The use property
Invokes another object in the same document as a prototype for this object. The content of this property is
either a SOM expression (which cannot start with '#') or a '#' character followed by an XML ID.

represents a SOM expression.
The XML ID or SOM expression is resolved in the context of the external document.
