I note that using Docbook 4.5 DTD I see:

file:///C%3A/download/open/xml/docbook-xml-4.5/dbpoolx.mod:7254: validity
error
: Redefinition of element code
<!ELEMENT code %ho; (%cptr.char.mix;)*>
                                       ^
validity warning : Attribute id of element code: already defined
 %common.attrib;
                ^
        lang            CDATA           #IMPLIED
        ^

 %code.role.attrib;
                   ^
role            CDATA           #IMPLIED
^

when building quickbook/boostbook docs, looks like the <code> element 
defined by the Boostbook DTD was introduced in Docbook-4.3 so the two DTD's 
now clash.  Is there any way we can fix this?  Maybe we should just require 
Docbook-4.3 and later and remove the <code> definition from Boostbook?
