From User Agent Accessibility Guidelines 1.0 (2002-12-17) | Glossary for this source

In this document, an "animation" refers to content that, when rendered, creates a visual movement effect automatically (i.e., without explicit user interaction). This definition of animation includes video and animated images. Animation techniques include: graphically displaying a sequence of snapshots within the same region (e.g., as is done for video and animated images). The series of snapshots may be provided by a single resource (e.g., an animated GIF image) or from distinct resources (e.g., a series of images downloaded continuously by the user agent).scrolling text (e.g., achieved through markup or style sheets).displacing graphical objects around the viewport (e.g., a picture of a ball that is moved around the viewport giving the impression that it is bouncing off of the viewport edges). For instance, the SMIL 2.0 [SMIL20] animation modules explain how to create such animation effects in a declarative manner (i.e., not by composition of successive snapshots).
This content type label refers to all of the requirements related to animations (including video and animated images) for the following checkpoints: 3.2, 4.4, and 4.5. When this label is part of a conformance profile, the user agent must implement at least one animation format. Furthermore, when this label is part of a profile, the user agent must satisfy the requirements of checkpoint 3.2 for all implemented animation formats, not just those identified in a conformance profile. The animation requirements apply to animation content that is recognized as distinct and that, according to the encoding format, may be rendered as a coherent unit.
