Please note that _character reference_ and _entity reference_ are distinct
categories.  In particular, the former is not an "entity" at all.

Not quite.  In the entity declarations, the entities are defined in terms
of character references.  That's OK, because the connection between
ISO-8859-1/UCS and the document character set is determined by the SGML
declaration.

Oops.  Not at all.  Absolutely not.  The encoding has absolutely nothing,
repeat **NOTHING** to do with this.  The I18n spec is required reading:

(It's the job of the "entity manager" to transcode from the encoding to
the document character set.)
