<p>The Reference Element (http://www.w3.org/TR/xmldsig-core/<font><span class="TYPE">sec-Reference</span></font>)</p>
<p>Reference is an element that may occur one or more times. It specifies
a digest algorithm and digest value, and optionally an identifier of the
object being signed, the type of the object, and/or a list of transforms
to be applied prior to digesting. The identification (URI) and transforms
describe how the digested content (i.e., the input to the digest method)
was created. The Type attribute facilitates the processing of referenced
data. For example, while this specification makes no requirements over
external data, an application may wish to signal that the referent is a
Manifest. An optional ID attribute permits a Reference to be referenced
from elsewhere.</p>
