| Oh, wait, I misunderstood--I thought docbookx.dtd was just for XML.

| <![%xml.features;[
| <!ENTITY euro "&#x20AC;"><!-- euro sign, U+20AC NEW -->
| ]]>
|
| Why is &#x20AC; restricted to XML documents?

Because SGML traditionally has used SDATA entities. There's a bug there, however,
in that if %sgml.features; is true, the entity declaration should be:

 <!ENTITY euro SDATA "[euro  ]"><!-- euro sign, U+20AC NEW -->

If adding SDATA fixes the problem, please let me know. If not, try
adding your own declaration for &euro; pointing to the Unicode code
point. That should work, if your SGML processor understands Unicode.

(SGML has all sorts of magic in the SGML Declaration to handle
multiple character sets.)
