Not fixed automaticallystructure, alt-text
What veraPDF reports
Formula structure element neither has an alternate description nor a replacement text
veraPDF rule 7.7-1 = ISO 14289-1:2014 clause 7.7, test 1, checked on PDF object SEFormula.
What the requirement says
All mathematical expressions shall be enclosed within a Formula tag as detailed in ISO 32000-1:2008, 14.8.4.5 and shall have Alt or ActualText attributes
Can it be fixed automatically?
Not fixed automatically. This failure needs the authoring tool or manual remediation; the automatic fix does not change it.
How to fix it by hand
Alternative text is human work: describe each image, formula or link in the authoring application (alt text field) or set it in the PDF editor's tag properties. No automatic tool can write a meaningful description for you.
