Yes, it is a bug in Java Xerces 1.2, which is the version
bundled with Xalan 1.2 right now.  But Xerces 1.2.1 is
available separately from http://xml.apache.org in the Xerces-J
area, and that version does work with the Docbook XML DTD.
Just put the new xerces.jar file in your CLASSPATH.

However, although Xalan 1.2 handles the html/docbook.xsl
stylesheet, it fails with the html/chunk.xsl stylesheet.
After parsing the file and the stylesheet without error,
Xalan fails in the transformation stage with:

  Transforming...
  Writing index.html for book
  Call to extension element failed:  File "http://www.jclark.com/xt" not found.
  Writing forward.htm for preface
  Call to extension element failed:  File "http://www.jclark.com/xt" not found.

Xalan doesn't seem to be falling back to the
Xalan extension if the XT extension doesn't work.

Saxon has no problem with chunk.xsl.
