transcoding

The wording regarding transcoding in the Character Model draft
(http://www.w3.org/TR/charmod/) needs some revision.

The definition of transcoding in section 3.3 notes that it does not
fix up encoding declarations.

Section 3.5 says that the interpretation of an entity as Unicode
characters "must be equivalent to transcoding the entity to some
Unicode encoding form and receiving it in that encoding form".

If an XML processor behaved in this way, it would have to report an
error for any non-Unicode entity, since it would be equivalent to
receiving an entity with an incorrect encoding declaration.
