[ Really about the XML spec, not the use of '&' in documents ]

I also support the conclusion that this doesn't restrict the actual
declaration to the example "shown below" ... I just can't interpret
the English (above) that way.  The spec could be changed so it has to
be read that way, but I see no reason to do so.  The restriction is
written to be on the semantics of the replacement text, not that one
character reference syntax be precluded.

While some XML (or SGML) processor might demand the literal text
found in the example, I'd call such insistence a bug.
