Many thanks Bob, that certainly did the trick.

Hi Mike,
The solution is to switch to the namespaced version of the DocBook XSL
distribution (docbook-xsl-ns-1.78.1) when processing DocBook 5
documents. When the non-namespaced stylesheets encounter a DocBook5
document in the namespace, it first tries to convert it to the
namespace. It seems there is a bug in that process for epub3. In
general, that conversion process presents other problems as well, so I
would recommend downloading and using the *ns* version of the
stylesheets.

Subject: [docbook-apps] EPUB3 default stylesheet throws NCX error
Hi List, I'm having an issue when running the default EPUB3
stylesheets on a document (see below for XML) as I'm getting an error
with the generated NCX file.
(I'm running on OSX Lion and I've referenced the stylesheets directly
for these examples)
$ xsltproc
http://docbook.sourceforge.net/release/xsl/1.78.1/epub3/chunk.xsl
test.xml
...
Generating NCX file ...
Request for title of element with no title: div (id="idp704")
Request for title of element with no title: code (contained in )
Writing OEBPS/toc.ncx for book
The NCX has an error in the title;
<docTitle><text>My First
Book???TITLE??????TITLE???</text></docTitle>
Also, the OPF has two extra itemref entries at the end of the <spine>.
If however I remove xmlns from the <book> node, it then works fine;
<book version="5.0">
This solution is obviously wrong as the XML then fails validation;
$ xmllint --relaxng http://www.docbook.org/xml/5.0/rng/docbookxi.rng
--noout test.xml
test.xml:2: element book: Relax-NG validity error : Expecting
element set, got book
test.xml:2: element book: Relax-NG validity error : Expecting a
namespace for element book
test.xml:2: element book: Relax-NG validity error : Did not expect
element book there
test.xml:2: element book: Relax-NG validity error : Expecting
element section, got book
test.xml:2: element book: Relax-NG validity error : Expecting
element setindex, got book
test.xml fails to validate
Perhaps it's related to my system - can I ask if anyone else gets the
same errors?
I haven't done any XSLT programming in four years and I'm new to
Docbook, so I want to make sure I have everything set up correctly
before I start customising.
Many thanks,
Mike Cook
