New Best Practice Guide for Mathematical Content in PDF

As technical documents often include sophisticated mathematical formulas, the need for standardized, accessible representations is clear. The new Best Practice Guide addresses this need by providing clear guidance on publishing accessible STEM content using MathML syntax within Tagged PDF.

A central theme is a strong recommendation to use PDF 2.0, which natively includes MathML as a standardized namespace and leverages Associated Files in support of accessibility. These features provide a standardized mechanism for embedding MathML and LaTeX representations as supplements to the visual PDF content, improving the experience for users who rely on assistive technology.
