Mobile Web Best Practices 1.0 User Agent (browser) developers are participants in the mobile value chain. The user agents for mobile devices should conform with UAAG [1] guidelines as appropriate. This is especially true now that some mobile devices have add-on assistive technology such as screen readers. The document's purpose is aimed more at content developers rather than the tools to render the content. Underlying this purpose is a continuing discussion of the limitations of the devices and user agents involved (such as screen size, color depth, input limitations, memory, etc.) Specific comments: section 3.1 which ever content adaptation implementation model is used, the model must retain necessary accessibility information (alt, label, etc.) and convey that information to the mobile device and the user. The following Best Practices Statements should reference UAAG checkpoints. 5.29 Refreshing, Redirection, and Spawned Windows should reference UAAG 2.4 Allow time-independent interaction (P1) - 1. For rendered content where user input is only possible within a finite time interval controlled by the user agent, allow configuration to provide a view where user interaction is time-independent. UAAG 3.5 Toggle automatic content retrieval (P1) 1. Allow configuration so that the user agent only retrieves content on explicit user request. 5.3.7 Background Images should reference UAAG 3.1 Toggle background images (P1) - 1. Allow configuration not to render background image content. 5.4.3 Structural Elements should reference UAAG 10.4 Provide outline view (P2) - 1. Make available to the user an "outline" view of rendered content, composed of labels for important structural elements (e.g., heading text, table titles, form titles, and other labels that are part of the content). This is all I am able to provide today.
