           Summary: [FO2.0Req] Print specific properties - Halftone
                    Screening Info
           Product: XSLFO
           Version: 2.0 Working Draft
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XSL-FO Requirements
        AssignedTo: xsl-editors@w3.org
        ReportedBy: j.tosovsky@tiscali.cz

In Chapter 8.3 of XSL 2.0 requirements there is list with several print
specific properties. I would add there also screening info, which could be
applied to every block element. Specification could be similar to PDF reference
at http://www.adobe.com/devnet/acrobat/pdfs/pdf_reference_1-7.pdf
(Chapter 6.4) and also Named Halftone dictionaries could be supported. Later
mentioned are described in section 6.4.4 (p.496): "Halftone dictionaries have
an optional entry, HalftoneName, that identifies the halftone by name." 

Such information could be transferred into PDF file and if such file would be
processed for offset printing on modern CTP devices, every object could be
rasterized with different settings which could even allow to combine halftone
and stochastic screening on single plate and significantly improve final
quality (for specific jobs).
