This early draft document explores situations for which the WCAG 2.x conformance model, and success criteria testability, are challenging to apply to a broad range of websites and web applications. The purpose of the document is to help understand these challenges more holistically, so that we can build better solutions in the future. For this initial draft, the challenges covered broadly fall into four main areas:
One of the reasons for publication of this document as a First Public Working Draft is to seek additional contributions describing any additional challenges, or further illustration of challenges in the existing identified areas below, ahead of work developing solutions. It is expected that a more thorough understanding of these challenges can lead to either a new conformance model, or an alternative model that is more appropriate for large, complex, and/or dynamic websites. Ideally, such a model would also be able to distinguish between websites that are substantially accessible for most visitors with disabilities most of the time, and websites that are largely unusable by a significant portion of visitors with a disability.
-======= -This early draft document explores situations for which the WCAG 2.x conformance model is challenging to apply to large, complex, and/or dynamic websites, web applications, and mobile applications. These challenges broadly fall into four main areas: (1) numerous WCAG Guidelines and Success Criteria expect human involvement to verify conformance, which is challenging to scale to large sites and to dynamic sites; (2) large and dynamic sites have portions that are always under construction, which is challenging to address with the WCAG 2.x conformance model which makes no allowance for that; and (3) third parties frequently add and change content on large and dynamic sites, and related non-conformities in such content make WCAG 2.x conformance significantly challenging; and (4) applying the WCAG 2.x conformance model to non-web information and - communications technologies (ICT).

This document also includes previously published research from the Silver Task Force and Community Group that was specifically related to Challenges with Conformance.
