Agreed.  The strawman proposal already covers encrypting
arbitrary objects.  After the Santa Barbara meeting, Joseph
and I discussed how to do what is suggested in your note.

Basically NodeType will be split into Type and Location and
EncryptedNode will be renamed EncryptedData so one would have
something like what you have in your message but with the
addition of a Type attribute and using the term "URI" rather
than "Location":

<EncryptedData xmlns="&xmlenc;"
  Type="bar"
  URI="foo"
  EncryptionInfo="#encryptionInfo23" />

Hi,

Something that I would be interested in is the ability to
provide encryption information about an external non-XML
entity:

<EncryptedData xmlns="&xmlenc;"
  Location="foo"
  EncryptionInfo="#encryptionInfo23" />

The rationale is that XML is being used in some situations
to encode control information describing accompanying non
XML data.

Support in this document would allow the control data to
express encryption information in a standard manner, and
the keying information could also be shared with encrypted
nodes within the control document.

Embedding external data within base 64 nodes is not always
practical or efficient.
