For my actual starting point I need to report element numerotation in a
before or after area. 
I suppose this can be handle by a hastable like solution. Every time an
element is encountered, 
the value may change and is reported anywhere outside the body of the page
model (I know to do that in the body area). 

So my need is very close to the XSL spec.

Another need for me is to compute an embedded index containing, for choosen
ancestor elements, small data (eg: a title)
for each page of the PDF document the element is present. I hope Markers can
help me to do that. That's like a Table of Content, but the table shows all
the pages of the document and the elements which are painted on each page
(generally the first one which appear on top of the page body). The table
contains as many rows as the document has pages. 

After doing that, I need to compute what I call a String page number
(different from physic page number, the one displayed by Acroread) which
behave like a chapter or subchapter numerotation (page : III.1.a, 
or page : 3.1.4.1.6). Also I hope Markers behaviour will help us to support
such numerotation. So I will be able to build table (of content or indexes)
containing the logical numerotation of the pages instead of the physical one
(actual one). Is this last need seems to be outside XSL specification ?
