PDF documents containing formulas generated by LaTeX are usually not accessible by assistive technologies for visually impaired people and people with special educational needs (i.e., by screen readers and braille displays). The axessibility package manages this issue, allowing to create a PDF document where the formulas are read by these assistive technologies, since it automatically generates hidden comments in the PDF document (by means of the /ActualText attribute or suitable tags) in correspondence to each formula.
