What the rule requires
A document must declare its language so screen readers pick the right pronunciation rules. Without the declaration, a screen reader falls back to its own default, and the text is read with the wrong pronunciation rules.
How Proof clears it
- Checks the declarations in both the document catalog and XMP metadata.
- Detects the language from content and writes the declaration when it’s absent — so screen readers pronounce correctly.

What to expect
Verify non-English detections. And passages in a second language are a separate check — language of parts (3.1.2) — surfaced with locations and attested by a human, because span-level language is a content decision.
