   The Reference Processing Model (section requires use of
   Canonical XML 1.0 [XML-C14N] as default processing behavior when
   a transformation is expecting an octet-stream, but the data
   object resulting from URI dereferencing or from the previous
   transformation in the list of Transform elements is a node-set.
   We RECOMMEND that, when generating signatures, signature
   applications do not rely on this default behavior, but explicitly
   identify the transformation that is applied to perform this
   mapping. In cases in which inclusive canonicalization is desired,
   we RECOMMEND that Canonical XML 1.1 [XML-C14N11] be used.
