W3C 是否提供了对增加级别（A 到 AAA）一致性的额外用户相关好处的解释
Does W3C offer an explanation of the additional user-related benefits of increased Levels (A through AAA) conformance
我不是要 "Level A: Meets all level A standards" 定义（这对律师或软件开发人员以外的任何人都毫无用处。）
我需要关于每个级别的那些能够传达其有用性的想法，以便我可以更好地描述为什么应该争取提高级别。
我发誓我曾经找到一个直接来自 W3C 的，但我已经搜索了好几天了，我再也找不到了。
三个一致性级别没有其他定义。 A为最低级，AAA为最高级。这些水平与残疾及其流行程度不符。
Understanding Levels of Conformance from the Working Group Note Understanding WCAG 2.0部分给出了一些“设置级别时评估的公共因素”的示例：
whether the Success Criterion is essential (in other words, if the Success Criterion isn't met, then even assistive technology can't make content accessible)
whether it is possible to satisfy the Success Criterion for all Web sites and types of content that the Success Criteria would apply to (e.g., different topics, types of content, types of Web technology)
whether the Success Criterion requires skills that could reasonably be achieved by the content creators (that is, the knowledge and skill to meet the Success Criteria could be acquired in a week's training or less)
whether the Success Criterion would impose limits on the "look & feel" and/or function of the Web page. (limits on function, presentation, freedom of expression, design or aesthetic that the Success Criteria might place on authors)
whether there are no workarounds if the Success Criterion is not met
因此，如果成功标准对于可访问性至关重要，易于实施，没有合适的替代方案，并且与大多数典型网站相关，则它更有可能获得一致性级别 A 而不是 AA/AAA.
不确定这是否是您要查找的内容，但它来自 Section508.gov 网站：
Level A (minimum) – Addresses the most basic web accessibility features, but does not generally achieve broad accessibility.
Level AA (mid-range) – Addresses most common barriers for disabled users and aligns to the Revised 508 Standards
Level AAA (highest) – Addresses the highest level of web accessibility, but is not recommended as a general policy, because it is not possible to satisfy all criteria for some content.
