由于万维网 (WWW) 目前是公众使用的主要基础设施，因此网站创建者需要构建普遍可访问的网站。可访问性指南（例如 Web 内容可访问性指南 (WCAG)）向创建者展示了如何制作可访问的网页。此外，还提供了自动验证给定网页是否符合指南的工具。尽管这些工具很有用，但将它们应用于除 HTML 之外的任何文档格式或除 WCAG 之外的任何指南都很困难，因为这些工具假定一组固定的指南（例如 WCAG）和固定的文档格式（例如 HTML）。也就是说，更改内置指南（例如，验证给定文档是否符合其组织定义的指南）需要修改工具。本文提出了一种简单明了的指南指定语言，并讨论了一种验证工具，该验证工具具有以下特点：指南规范与工具分离，易于修改；可以验证任意XML文档；该工具不仅可以用于辅助功能指南验证，还可以用于复杂的语法检查。我们还展示了使用我们的验证工具对美国和日本 40 个主要组织的约 3,000 个网页进行的验证结果。
Since the World Wide Web (WWW) is currently the principal infrastructure used by the general public, Web site creators are required to build universally accessible sites. Accessibility guidelines such as the Web content accessibility guidelines (WCAG) show the creators how to make accessible Web pages. Also, tools which automatically verify whether or not a given web page complies with the guidelines are provided. Although those tools are useful, applying them to any document format other than HTML or any guidelines other than WCAG is difficult, since these tools assume a fixed set of guidelines (e.g., WCAG) and a fixed document format (e.g., HTML). That is, changing the built-in guidelines (e.g., verifying whether a given document complies with the guidelines defined by their organization) requires modifying the tool. This paper proposes a simple and clear language for specifying guidelines, and discusses a verification tool which has the following characteristics: a guideline specification is separated from the tool and can be easily modified; an arbitrary XML document can be verified; and the tool can be used not only for accessibility guideline verification but also for complex syntactic checking. We also present the verification results conducted on about 3,000 Web pages of forty major organizations in the U.S.A. and Japan using our verification tool.
