Re: [xsl] how to remove the duplicate back page

Hi Tony,
Thank you for your very thoughtful comments.
> Does that mean that the problem is solved?
--> unfortunately, the problem has not been solved properly, as said,
there is duplicate of the back page in the final PDF. triggering a new
page sequence was solved, thanks largely to the code you comitted. To
avoid confusion, I have changed the subject line of this email.

--> Sorry if I have mixed the problem and the solutions in my post. My
problem was initially to seek a method by which the element having
'outputclass="pagebreak"' , which should be appearing on the 'Back
Page' in result PDF, must force a new page, because previously,  all
elements were populated within a single page sequence, hence leading
to the fact that in the final PDF, all Heading and sections cannot be
divided, there is no Heading starting a new page. I then figured out I
need to trigger a new FO page sequence for that specific element so as
to force a new page, this has been solved perfectly, thanks to your
code.
However, the side effect, as it now turns out, there is two 'back
page' in the resulting.
My problem has now become how to remove one of them. Once again,
'outputclass="pagebreak" can be attached to as many elements as
needed, while the element that shall be part of the 'Back Page' in the
final PDF must have it. Please refer to the following when you desire
to examine input.
 ---------------------------------------
 <Map>
 <concept id=GUID-1234 outputclass="pagebreak">
  <title> Overview</title>
  <conbody/>
 </concept>
 <concept id=GUID-5678>
   <title>Basics</title>
  <conbody/>
 </concept>
 <concept id=GUID-1342 outputclass="pagebreak">-------------> This
belongs to the 'Back Page' on a new page.
 <title>Explore and get support</title>
 <conbody/>
 </concept>
 </map>
 ---------------------------------------
I apologize if this post has been sloppy and poorly written in the
past couple of days.
Hope this clarifies.
