page headers for <article><section>

[Ron Catterall <ron@catterall.net>]

Hi

I'm having problems trying to get article title as header on even 
pages and section title as header on odd pages for a very simple 
simple document (an article built out of sections and appendices) 
(DB5, 1.73.2, Saxon 6.5.5, XEP4.9).  A simplified version of the xml 
and xsl files is below.  Files to generate sufficient pages to 
demonstrate the problem are attached: test.xml and test.xsl and the 
pdf output, test.pdf

(For a book everything works fine as in Bob's book pp.196-7.)

The header on the odd pages (centered of course) is:
      Title of first sectionTitleof article
(i.e. a concatenation of the correct section and article titles) and so on:
      Title of second sectionTitle of article.
etc
The header on the even pages is correct:
      Title of article
and as expected

Replacing the <retrieve-marker>/<apply-templates> section by:
<xsl:value-of  select="ancestor-or-self::d:article/d:section/d:info/d:title"/>
results in picking up the title of the first section and using that 
for ALL odd pages right through the appendices.

Can anyone help?
