A more fundamental question:

The XML decrypt transform, operating on XML data,
could be concisely defined as follows:

* Clone the input node set into a new document;
  a.k.a. serialize and decrypt the node set.

* Process every unexceptional EncryptedData element
  in this new document in decrypt-and-replace mode.

* Return the resulting document.

Now, there are a few bugs and such (same-document
references and what have you), however:

Why do we specify, in minute detail, how to perform
decrypt-and-replace in the decrypt transform spec,
and not in the XML encryption spec.

At the n'th blush, it seems to me that the decrypt
transform is having to make up for a (deliberate)
lack of detail about processing encrypted XML data
in the core spec.

This somewhat encompasses my concerns about how to
interpret the Type of an EncryptedData.
