[NTG-context] tagged pdf (again)

I'm not on the pdftex list, but I was just looking through their archives and came across this document on the PDF 1.5 spec: http://partners.adobe.com/asn/acrobat/docs/filefmtspecs/ PDFReference15draft.pdf The most notable point of interest to me is on the extensions to the tagged PDF spec (particularly starting on 10.7.4). PDF will now support structured markup for pretty much all of the common structures in ConTeXt, even citations! Any chance we'll finally see pdftex (and later ConTeXt) support this Hans? Bruce
