Axessibility 2.0: creating tagged PDF documents with accessible formulae

PDF documents containing formulae generated by LATEX are usually not accessible by assistive technologies for visually impaired people (i.e., by screen readers and Braille displays). The LATEX package axessibility.sty that we developed manages this issue, llowing to create PDF documents where the formulae are read by such assistive technologies, through the insertion of hidden comments. In this paper we describe the evolution of the package, that now automatically generates also the tagging of the formulae. The package does not generate PDF/UA.
