+The challenges covered broadly fall into five main areas:
Accessibility Supportedin the many provisions +tied to use with assistive technologies and platform accessibility +features, combined with the lack of definition of what constitutes +Accessibility Supported, further exacerbates the need for expert +human judgement (\#1 above), as well as potential different and +non-overlapping sets of these features used when including 3rd +party content (\#3 above).
The purpose of this document is to help understand those challenges more holistically, and explore approaches for mitigating them so that we can address such challenges more fully in future accessibility guidelines including the forthcoming W3C Accessibility Guidelines (WCAG 3.0) (now in early development) where the W3C Working Group Charter expressly anticipates a new conformance model.

We know of no useable mitigations to achieve the Accessibility Supported
conformance requirement for public facing web sites. WCAG-EM's Second Note suggests that: For some websites in closed networks, such as an intranet website, where both the users and the computers used to access the website are known, this baseline may be limited to the operating systems, web browsers and assistive
technologies used within this closed network.
It continues saying: However, in most cases this baseline is ideally broader to cover the majority of current user agents used by people with disabilities in any applicable particular geographic region and
