[Commentor] LC-437 Al Gilman on behalf of WAI [Working Group decision] We think that UAAG is out of scope as the document is about delivered content rather than user agents. But after further discussion with the WAI CG, we have added an appendix (Appendix B, Related Reading) linking to the existing WAI Guidelines and Techniques. [Commentor reply] yes [Comment] 
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.) [linkage opportunity from WAI document] (1) I can imagine a full version of the doc playing the same role in the ATAG conformance model that WCAG does (i.e. as a standard that an authoring tool guides the author towards conformance with). Perhaps a note to this effect can be put into ATAG 2.0. [linkage opportunity from MWBP document] (2) Clearly all the adaptive stuff in the doc would require authoring tool support. Therefore, the Mobile Web group might consider putting in an informative note about the role of authoring tools (and ATAG) just as WCAG has. This is the text of the WCAG 2.0 note: " A large part of Web content is created using authoring tools. These tools often determine how Web content is implemented, either by making authoring decisions directly or by limiting the choices available to the author. As a result, authoring tools will play an important role in creating Web content that conforms to the Web Content Accessibility Guidelines. At the same time, we recommend that all authors become familiar with the Guidelines because this will help in creating accessible content and coverage of the Guidelines may vary between tools. Developers of authoring tools can help to make their tools more aware of the Web Content Accessibility Guidelines by following the Authoring Tool Accessibility Guidelines. We encourage users and purchasers of authoring tools to consider conformance to the Authoring Tool Accessibility Guidelines as a criterion when selecting tools. "
