The only reader that can currently make use of MathML embedded as associated file is Foxit together with a beta version of NVDA and a current MathCat. See https://latex3.github.io/tagging-project/documentation/wtpdf/fulldoc for some discussions. To find and use the associated MathML file Foxit requires that it is attached to a Formula element in the PDF 2.0 namespace: https://github.com/foxitsoftware/PDF_UA-2. context attaches the MathML to a `math` element declared in a context specific namespace and then rolemapped (like all other structure elements) to the NonStruct structure element (which as the name implies has no semantic meaning). This means that this MathML is not seen by any reader and useless. If some math is read then simply in the amount reader can extract math from untagged PDFs. -- Ulrike Fischer http://www.troubleshooting-tex.de/ ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___________________________________________________________________________________
