Okay.  So a transcoder must be able to notice what is and what is not
encrypted, and a decryptor must (in the general case) be able to
transcode from UTF-8.

This seems bizarre.  A partially encrypted document on this view is not
XML at all, but XML-with-interruptions: a sequence of characters,
then raw octets, then more characters.

Or are the encrypted octets themselves represented as characters
in the XML (which is then represented as octets)?
