  I have not only the character entity references, but also the general
entity references:

[code]
<!DOCTYPE doc [
...
<!ENTITY site "<a href='http://uucode.com/'>homepage</a>">
]>
<doc>Visit the &site;</doc>
[/code]

  In this case the entity "site" defines a part of the XML document
structure.

  Quite nice. I've accepted your "&" form for my needs. Thanks.

  I want to process a document with entities and don't want to lose
entities in the document after processing. That's why I need the new form.
And, with some accuracy, SXML tools can be used.
