I'm not sure I understand this, I'll defer to the authors. <smile/>

We discussed the scenario below in September and Hiroshi suggested we would 
need a new function:
  Instead, we should define a new function that decrypts an
  xenc:EncryptedData element with a type other than Element
  or Content to an octet stream.  Also we have to state that
  when such an xenc:EncryptedData element is being
  decrypted, the input to the transform has to be a node-set
  that has the xenc:EncryptedData element as the first node.

As is my tendency I tend not to push for something unless someone says they 
want it. Hiroshi/Takeshi, is Merlin's usage scenario the same as what you 
were thinking? If so, would you like to propose some text?
