Human language detectable

foundational

Normative Text

The human language of all content within the view is programmatically determinable.

Except when

  • a language tag is not available in ISO 639 language codes, or
  • the technology used to create the view does not support indicating languages.
Tests

This section is non-normative.

Procedure

For text content:

  1. Establish which language is used.
  2. Check that the content’s language is identified in the HTML code with a lang attribute.

Expected results

  • #2 is true.

Tests

This content needs to be written.

Key Terms

accessibility support set

group of user agents and assistive technologies you test with

The AGWG is considering defining a default set of user agents and assistive technologies that they use when validating guidelines.

Accessibility support sets may vary based on language, region, or situation.

If you are not using the default accessibility set, the conformance report should indicate what set is being used.

accessibility supported

available and working in the user agents and assistive technology in the accessibility support set

The working group intended to include a default accessibility support set. See Default accessibility support set #277.

actively available

available for the user to perceive and use

conformance scope

A set of Views and/or Pages selected to be part of a conformance claim. Where a View or Page is part of a Process, all the Views or Pages in the process must be included.

How a person or organization selects the set is not defined in WCAG3. There maybe informative guidance on selecting a suitable set in future (similar to WCAG-EM), but regional laws or regulations may provide a methodology.

content

information, sensory experience and interactions conveyed

human language

language that is spoken, written, or signed (through visual or tactile means) to communicate with humans

See also sign language.

page

non-embedded resource obtained from a single URI using HTTP plus any other resources that are used in the rendering or intended to be rendered together

Where a URI is available and represents a unique set of content, that would be the preferred conformance unit.

platform

software, or collection of layers of software, that lies below the subject software and provides services to the subject software and that allows the subject software to be isolated from the hardware, drivers, and other software below

Platform software both makes it easier for subject software to run on different hardware, and provides the subject software with many services (e.g. functions, utilities, libraries) that make the subject software easier to write, keep updated, and work more uniformly with other subject software.

A particular software component might play the role of a platform in some situations and a client in others. For example a browser is a platform for the content of the page but it also relies on the operating system below it.

The platform is the context in which the conformance scope exists.

process

series of views or pages associated with user actions, where actions required to complete an activity are performed, often in a certain order, regardless of the technologies used or whether it spans different sites or domains

programmatically determinable

meaning of the content and all its important attributes can be determined by software functionality that is accessibility supported

sign language

a language using combinations of movements of the hands and arms, facial expressions, or body positions to convey meaning

view

content that is actively available in a viewport including that which can be scrolled or panned to, and any additional content that is included by expansion while leaving the rest of the content in the viewport actively available

A modal dialog box would constitute a new view because the other content in the viewport is no longer actively available.

viewport

object in which the platform presents content

The author has no control of the viewport and almost always has no idea what is presented in a viewport (e.g. what is on screen) because it is provided by the platform. On browsers the hardware platform is isolated from the content.

Content can be presented through one or more viewports. Viewports include windows, frames, loudspeakers, and virtual magnifying glasses. A viewport may contain another viewport. For example, nested frames. Interface components created by the user agent such as prompts, menus, and alerts are not viewports.
