I don't think I can speak very well to the functionality or requirements of
this feature, but I believe the spec says the actual data referenced is the
thing pointed to by a Reference. Kind of awkward I agree... good ideas are
welcome!

4.3.3 The Reference Element
The optional Type attribute contains information about the type of
object being signed. This is represented as a URI. For example:
Type="http://www.w3.org/2000/02/xmldsig#Object"
Type="http://www.w3.org/2000/02/xmldsig#Manifest"
Type="http://www.w3.org/2000/02/xmldsig#SignatureProperty"
The Type attribute applies to the item being pointed at, not its
contents. For example, a reference that identifies an Object element
containing a SignatureProperties element is still of type #Object. The
type attribute is advisory. No validation of the type information is
required by this specification.
