Controls, Input: If non-text content is a control or accepts user input, then it has a name that describes its purpose.

Time-Based Media: If non-text content is time-based media, then text alternatives at least provide a descriptive identification of the non-text content.

Test: If non-text content is a test or exercise that would be invalid if presented in text, then text alternatives at least provide a descriptive identification of the non-text content.

Sensory: If non-text content is primarily intended to create a specific sensory experience, then text alternatives at least provide a descriptive identification of the non-text content.

CAPTCHA: If the purpose of non-text content is to confirm that content is being accessed by a person rather than a computer, then text alternatives that identify and describe the purpose of the non-text content are provided, and alternative forms of CAPTCHA using output modes for different types of sensory perception are provided to accommodate different disabilities.

Decoration, Formatting, Invisible: If non-text content is pure decoration, is used only for visual formatting, or is not presented to users, then it is implemented in a way that it can be ignored by assistive technology.
