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

See also sign language.
legal information: content that must be provided to meet statutory or regulatory requirements, or that provides legal protection such as terms and conditions
nested clause: clause that is embedded inside another clause and neither clause can stand alone as a sentence

Nested clauses use groups of words that are sometimes called dependent clauses or subordinate clauses.

“I know the teacher who said the book that you lent me was missing.” The main or independent clause is “I know the teacher”. It includes the dependent or subordinate clause “who said the book … was missing”, which includes the nested clause “that you lent me”.
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
text: sequence of characters that can be programmatically determined, where the sequence is expressing something in human language
text content: text and formatting that, together with the semantic or hierarchical structure provided by markup, communicate the content and meaning
