Checkpoint 2.1 : Render content according to specification
Render content according to format specification (e.g., for a markup language or style sheet language).
Normative inclusions and exclusions
Rendering requirements include format-defined interactions between author preferences and user preferences/capabilities (e.g., when to render the alt attribute in HTML, the rendering order of nested OBJECT elements in HTML, test attributes in SMIL, and the cascade in CSS2).
When a rendering requirement of another specification contradicts a requirement of UAAG 1.0, the user agent may disregard the rendering requirement of the other specification and still satisfy this checkpoint; see the section on the relation of this document to general software design guidelines and other specifications for more information.
The user agent is not required to satisfy this checkpoint for all implemented specifications; see the section on conformance profiles for more information.
This checkpoint excludes the requirements of checkpoint 2.6.
