object-text-alternative-quality
<object> text alternative must be appropriate (manual review)
Flags <object> elements with detected fallback or name for human review of equivalence and appropriateness.
Applies to. Applies to <object> elements that already carry a text alternative: fallback text content, a non-empty aria-label, an aria-labelledby that resolves to non-empty text, or a non-empty title. An <object> with none of those is object-text-alternative-present's failure, not a quality question. The element must be included in the accessibility tree, and role="presentation"/"none" takes it out of scope unless it is focusable, which restores its role.
Expectation. Human review is required to confirm that the provided text alternative is accurate and appropriate.
Examples
<object data="brochure.pdf" type="application/pdf">Product brochure (PDF)</object>
Fallback text is present — worth confirming "Product brochure (PDF)" is genuinely equivalent to the embedded document, not just a filler caption.
<object data="brochure.pdf" type="application/pdf"></object>
No fallback content, ARIA name, or title exists to review; that's `object-text-alternative-present`'s failure instead.
