A cooking robot support portal may offer a translated guide yet leave important language information unexplained. A buyer can read the page visually and still lack evidence about how its main language and foreign language passages are identified in the delivered web content. This acceptance task concerns support documentation. It does not establish that a cooking process is safe or that a robot understands a spoken instruction.
A menu promising several languages describes a navigation choice. The page reached through that menu is the object that needs review. Ask the supplier to identify the particular support page, its intended audience and the content revision included in the handover. A translated heading on an otherwise unchanged page should not become evidence that the entire guide has been reviewed.
Consider a fictional portal containing a local language introduction, an imported supplier note and a product name that remains unchanged. These pieces need not all be treated identically. The receiver should first understand the editorial intent of each passage. That gives the technical reviewer a defined page to inspect rather than a broad request to make every foreign-looking word behave the same way.
W3C's Language of Page explanation concerns programmatically identifying the default human language of a web page. It describes why this information matters for presentation by user agents and assistive technologies. The criterion provides a question for web delivery; it is not a certification of the quality of the translation itself.
For acceptance, ask the supplier to show where the delivered page identifies that default and to explain whether it matches the actual main text. Keep the evidence linked to the page revision. A screenshot of the language selector does not answer this question, because the selector can be visually correct while describing a different page or a different state of the portal.

The separate W3C explanation for Language of Parts addresses passages or phrases. It also sets out exceptions, including proper names, technical terms, indeterminate language and expressions adopted into the surrounding vernacular. A reviewer should retain these qualifications rather than assuming that every imported product term requires the same treatment as a full foreign language paragraph.
In the imagined supplier note, a complete explanatory paragraph would prompt a different editorial question from an unchanged model name. Identify the boundaries of the paragraph and ask what language it uses. Do not decide from a typeface or a flag icon alone. If a term has several possible readings, request clarification from the content owner before presenting a technical implementation as a settled editorial answer.
This distinction also helps procurement teams avoid an unhelpful blanket requirement. A clear acceptance note can identify the default page language and separately record which passages were reviewed for language changes. An indiscriminate instruction to tag every unfamiliar token can obscure the intended reading rather than document it.
If the contract includes an accessibility demonstration, agree on the page revision, browser and assistive technology involved, and retain the actual observations. A reviewer should be able to tell whether the demonstration concerned the main text, an embedded passage or navigation between versions. This article reports no such demonstration and makes no claim about a particular screen reader's output.
Do not extend a successful web observation into a claim about the robot's microphone, language recognition or spoken response. Those functions involve different interfaces and different evidence. Likewise, editorial language identification cannot establish recipe correctness, allergen handling or food preparation performance. The procurement record should name the function it actually examined.
A handover worksheet can give each mixed language passage its own location and owner. That is useful when the translation team and the web supplier are different organizations: the former can settle the intended reading, while the latter explains its implementation. Keep both responses rather than closing the issue after receiving only a screenshot of a revised menu.

When the supplier revises the page, associate the response with the original passage and the new revision. Check that any changed language boundaries still match the actual wording. If the content owner has not decided what a passage is intended to say, keep that question open even when a markup change has been delivered. Technical and editorial decisions can be related without being interchangeable.
The original diagrams illustrate page and passage relationships, not a real cooking robot or an accessibility test. The cooking robot documentation section and article index provide routes to other procurement topics. A precise language handover helps the next reviewer understand the web content being supplied while preserving the limits of the evidence collected.
