Excellent. I have the following suggestions:
1) Any S characters should be allowed in base64 content, but ignored.
That agrees with the normal use of Base64, where line end characters
are typically added every 64 characters or so.
2) xml:packed should be a notation attribute, and W3C should define
a public ID for Base 64 notation, based on RFC 2045.
3) It should be pointed out that this is a typical example of
notation-governed elements. At the moment, the use of notation
attributes in XML is not well motivated by the Recommendation.
