Currently accourding to ps2pdf.htm "ps2pdf ignores the PDF 1.3 (Acrobat 4.x) pdfmarks related to document content structure: StRoleMap, StClassMap, StPNE, StBookmarkRoot, StPush, StPop, StPopAll, StBMC, StBDC, EMC, StOBJ, StAttr, StStore, StRetrieve, NamespacePush, NamespacePop, and NI. While this causes some structural information to be omitted from the output file, the displayed and printed output are normally not affected.". In order to produce tagged PDF files (which are required for government agencies) the processing of this kind of pdf is crucial so it will be nice to see this feature in GS working.
We would like to have a sample file, and want to know what application and/or driver creates these pdfmarks. Also please describe the "required for government agencies" -- what agencies? -- is there a FIPS or other specification that describes this? We are marking this bountiable in case someone from the outside wants to develop this.
Passing to Ken since he handles pdfwrite from now.
Enhancement still missing in Ghostscript 9.03
