AccessibilityOperation Class    

Operation to make a document accessible.

Accessible or Tagged PDFs are the same as normal PDFs but have been annotated with metadata in the form of PDF tags. This metadata is required because PDF documents contain good layout information but little semantic structure. The tags that are required supply this semantic structure. The way they are inserted and operate is defined in the Adobe PDF Specification.

See the MakeAccessible function for further information on accessibility standards and tagged PDF.
