PDF Accessibility | Fixing the Specified Language for Alt Elements

Last updated: September 2025

Issue: Unable to determine the language of the Alt attribute of the element.

Meaning:  The Alt (alternative text) attribute for an element lacks a specified language, which may cause screen readers to mispronounce or improperly interpret the description.

Fix: Check for accessibility and select the document's primary language.
