Re: [docbook-apps] Footer odd/even page problem when chapters do not begin on an odd page

["Bob Stayton" <bobs@sagehill.net>]

OK, I think the problem here is that in some cases you want an odd-numbered page to 
put the page number on the left, and in other cases on the right, depending on the 
preceding page count. I don't see how to do that in XSL-FO.

The footer.content template in fo/pagesetup.xsl has this choice (simplified somewhat):

      <xsl:when $sequence = 'odd' and $position='right'">
        <fo:page-number/>
      </xsl:when>

Here 'odd' is the number of the current page, and 'right' is the footer location on 
the current page.  You could change this statement from 'right' to 'left' and it would 
work for your current book, but not for others.

XSL-FO does not have the concept of 'right' and 'left' *pages*.  It only keeps track 
of page numbers, and those numbers can be even or odd.  How those odd and even pages 
are assembled into a book of left and right spreads is outside the scope of XSL-FO.

I think it operates under the convention that is common in the publishing industry 
that when you produce a left-to-right reading document that the first page has the 
binding on the left and is numbered 1, making it the right-hand page in the spread 
with the page number on the right.  Only when you have a right-to-left reading 
document such as Hebrew or Arabic is that reversed, but then so is everything else.

Hmm, sorry, I messed up the explanation.

That's exactly right, although the issue is not with the numbering:
the left-hand page is numbered with "1" and the right-hand page is
numbered with "2" already.

The issue is that the footer layout is reversed.
