Instances of this class act as a reference to the signed data,
expressed as a URI (using the Uri property) or as
a local reference to an instance of the DataObject
class (using the Id property). References are
associated with a signature through the
SignedXml.AddReference( ) method.
Implementations of the Transform class can be
added to a reference with the AddTransform( )
method; the transformations will be applied in order before the data
is signed. The algorithm used to create the cryptographic hash code
is set with the DigestMethod property—the
default value is http://www.w3.org/2000/09/xmldsig#sha1, which
specifies the SHA-1 hash algorithm.
