Sorry, not sure I understand. If you are asking how to create an accessible PDF document, there are many resources available to you. Two good places to start are the W3C's Web Content Accessibility Guidelines (WCAG) 2.0 Techniques for PDF Accessibility, and the Adobe Acrobat X Professional: PDF Accessibility (Section 508 Tagging) Reference Guide, created by some of my colleagues in California public service.
Hope this helps. If not, please follow up with specifics.
