At the lowest level of conformance, there is guidance on how to handle it, to wit: prompt the author for information that is missing but necessary, and if it is still not provided, warn the author before the content is saved that the resulting content will not meet WCAG A. At higher levels, this is covered in even more detail. Here are some of the relevant techniques for level A conformance: * Technique B.1.3.1-1 [Sufficient]: Ensuring that any action that the authoring tool takes without complete author knowledge that causes content to be added or modified has the result of not introducing new contraventions of the level "A" Web content accessibility benchmarks. * Technique B.1.3.1-2 [Advisory]: Using prompting to elicit information from the author when necessary (see Guideline B.2.1). http://www.w3.org/TR/2008/WD-ATAG20-TECHS-20080310/#gl-tool-conventions-scA And: B.2.1.1 Prompt "A" Accessible: If authors are prompted for any information as content is being added or updated (e.g., by an image insertion dialog), then the tool also prominently prompts for any accessibility information required for that content to meet the level "A" Web content accessibility benchmarks. * Technique B.2.1.1-1 [Sufficient]: Ensuring that, whenever content that requires accessibility information from the author in order to agree with the level "A" Web content accessibility benchmarks is added/updated, the author is informed of the need for the additional information by prompting mechanisms that are appropriate for the type of information in question (see Appendix A: Prompting for Various Types of Accessibility Information). * Technique B.2.1.1-2 [Advisory]: Grouping input controls when several pieces of accessibility information are all required from the author as part of an accessible authoring practice. * Technique B.2.1.1-3 [Advisory]: Checking all author responses to prompts for spelling, grammar, and reading level (where applicable). B.2.1.2 Warn "A" Accessible: If an authoring action or instruction will always lead to the creation of content that cannot be made to meet the level "A" Web content accessibility benchmarks other than by making an alternative version, then a warning is displayed. * Technique B.2.1.2-1 [Sufficient]: Ensuring that all instruction text that, if followed exactly by the author, leads to content being created or modified so as to meet the level "A" Web content accessibility benchmarks. * Technique B.2.1.2-2 [Sufficient]: Consistently labeling help documents or other documentation that, if followed exactly by the author, would lead to content being created or modified to not meet the level "A" Web content accessibility benchmarks. http://www.w3.org/TR/2008/WD-ATAG20-TECHS-20080310/#prompt-user-scA - m
