> This patch allows the merging of Tagged PDF.  
> Known Limitations :
> -Only PDF with marked-content sequences in the page content stream are 
> supported. Marked-content sequences in content stream other than the content 
> stream of the page are not supported.
> -Repeated headers and footers are not completely supported. Example: 2-page 
> pdf including table that spans both pages with repeated header. If you merge  
> the second page, the table header will be visible in the pdf but the reader 
> will ignore it (same principle applies for repeated footers).
> In order to use this feature, accessibility must be enabled in the 
> configuration file and the source pdf must be accessible (tagged).
> The fo, configuration and the source pdf of a simple example is included. 
> Also included, are the pdf-plugin junit tests. Necessary jars and pdf are 
> included in the pdfpluginbinaryfiles zip.
> Branch:
> https://svn.apache.org/repos/asf/xmlgraphics/fop-pdf-images/branches/Temp_MergeTaggedPDF
