[xsl] FW: XSL-FO: reset fo:page-number to 1 in each section of .pdf, ba sed on XML input

["Greenbaum, Bill" <Bill@xxxxxxxxxxxx>]

> Objective: Generate a .pdf with FOP, showing the <fo:page-number/>
> reverting to 1 on the first page for each BIRD.
> 
> What I get now: The output .pdf displays page numbers running
> consecutively from 1 at the beginning output to the end of the entire
> output.
> 
> Environment: Win, Apache's FOP-0.20.4 tool, generating a .pdf from an .XML
> file and an .XSL file (see samples below), . 
> 
> XML input: Each DOCUMENT/ITEM tag contains one BIRD tag with other data
> pertaining to that BIRD.  Different ITEMs can contain the same BIRD value.
> For each FOP transformation, I don't know in advance how many different
> BIRDs will occur in the XML, nor how many <ITEM>-level tags will pertain
> to the same BIRD value.   I'd like to assume I don't need to restructure
> the XML to reach our objective (correct pagination).
