Summary
Written by Judy Brewer, Director of the W3C Web Accessibility Initiative, this paper provides an authoritative overview of the state of web accessibility standards and their implementation as of 2004. Brewer describes the three complementary WAI guidelines — WCAG 1.0 (for web content, a W3C Recommendation since 1999), ATAG 1.0 (for authoring tools, since 2000), and UAAG 1.0 (for browsers and media players, since 2002) — and explains how they form an interdependent system where all three must be implemented to achieve comprehensive accessibility. The paper reports that while WCAG 1.0 had been widely adopted by governments internationally, implementation of UAAG and ATAG by browser and authoring tool developers remained only incremental and had not yet significantly impacted the accessibility of the web. Brewer describes the early development of WCAG 2.0, then in Working Draft status, noting that feedback on WCAG 1.0 indicated the need for guidelines that addressed more advanced web technologies, were more understandable to different audiences, easier to implement, and more precisely testable. The paper examines evaluation methodology, emphasizing that automated tools alone cannot determine conformance and that manual expert evaluation combined with testing by users with disabilities is essential for comprehensive accessibility assessment.
Key findings
Brewer identified several critical issues affecting web accessibility progress. On evaluation, she noted that no automated tool could determine full conformance to any WCAG 1.0 priority level, and that anomalous survey results — such as US sites showing higher WCAG 1.0 Level A conformance than Section 508 conformance despite Section 508 being essentially a subset of WCAG Level A — could be traced to confusion about automated versus manual testing. On standards harmonization, she warned that fragmentation of accessibility standards across national, provincial, and organizational levels was creating problems for organizations serving multiple regions, and that this fragmentation undermined market demand for accessible authoring tools and browsers. Brewer identified the strategic importance of authoring tools: if they automatically produced valid markup, prompted for accessibility information, and performed pre-publishing checks, even untrained developers could produce accessible sites. She also debunked persistent myths: that assistive technology alone could compensate for inaccessible content (the 'silver bullet' myth), that WCAG alone was sufficient without accessible browsers and authoring tools, that text-only sites were an adequate accessibility solution, and that accessible sites must be visually unappealing.
Relevance
This paper captures a pivotal moment in accessibility standards history — the transition period between WCAG 1.0 and the eventual release of WCAG 2.0 (which would not become a Recommendation until December 2008, four years later). Brewer's analysis of why standards harmonization matters proved prescient: the fragmentation she warned about led to years of confusion as different countries adopted varying interpretations of accessibility requirements, a problem that WCAG 2.0's technology-neutral approach was designed to address. Her emphasis on the complementary nature of content, authoring tool, and user agent guidelines remains a fundamental insight that is often overlooked — organizations focus on WCAG conformance while neglecting to demand accessible tools from their vendors. The authoring tool accessibility gap she identified persists today: most content management systems and web development tools still do not adequately prompt for or enforce accessibility features. For practitioners, the paper's framework of automated testing plus expert evaluation plus user testing remains the gold standard for comprehensive accessibility assessment.
