DOCBOOK-APPS: < in saxon

I am getting this error.

xml:

	<para><screen>
		C:\bootcd1> mkisofs.exe -N -l -no-iso-translate
-relaxed-filenames -v -o C:\cd.iso disk1 
		C:\bootcd1> mkbootcd.exe C:\cd.iso - <
mkbootcd.txt</screen></para>  (<---line 150)
	  </listitem>
	</orderedlist>
      </sect1>



java com.icl.saxon.StyleSheet -o index.html mydoc.xml
..\emacs\sgml\stylesheets\dbx129\docbook\html\docbook.xsl
Fatal error reported by XML parser: name expected (found " ")
  URL:    file:mydoc.xml
  Line:   150
  Column: 42
Error
  org.xml.sax.SAXParseException: name expected (found " "): name expected
(found
 " ")
Transformation failed

It's the in/output feed character (<). How do I make this work? Bug in
saxon?

Thanks,

mk
