DsPdf provides the means for you to create PDF/UA-2 compliant documents. PDF/UA-2 is the second version of the PDF/Universal Accessibility standard, describing how to create accessible PDFs for use with assistive technologies such as screen readers. It is based on PDF 2.0 and imposes stricter requirements on the document's structure tree than PDF/UA-1, including namespace declarations and a root "Document" structure element. This sample also shows "Structure Destinations" - outline entries that point at a structure element instead of a page location. Note that this is a very new PDF 2.0 mechanism: neither the DsPdfViewer used in these demos, nor Adobe Acrobat, currently resolve it, so clicking a bookmark may not navigate to its target even though the destination itself is generated correctly.
