For non-text content, provide text equivalents that serve the same purpose
or convey the same information as the non-text content, except when the sole
purpose of the non-text content is to create a specific sensory experience
(for example, music and visual art) in which case a text label or
description is sufficient.
Allow users to control time limits on their reading or interaction unless
specific real-time events or rules of competition make such control
impossible.
