One approach to the "user agent capability" problem, which I don't think has been clearly enunciated thus far, would be as follows: 1. To make it clear that socio-economic factors, which may be a direct or indirect result of various forms of discrimination, can affect access to computing resources and may thus preclude certain individuals and groups from taking full or immediate advantage of recent developments in user agent software and/or assistive technologies. 2. To acknowledge openly that any firm criterion as to when a particular technology or feature has become so widespread as to be available, for practical purposes, to everyone who uses the web, is bound to be somewhat arbitrary and to exclude certain individuals who, for whatever reason, have not upgraded their hardware and/or software. 3. To state that, for the purpose of defininng conformance to the guidelines, such socio-economic considerations will not be taken into account, but that implementors of the guidelines should bear them in mind in deciding to what extent their content should be backward compatible. Thus, implementors would be free, within certain limits, to weigh the advantages of backward compatibility against other factors, such as the added convenience, improved features and reduced development costs which may be associated with newer technologies. 4. To prescribe, for purposes of conformance to the guidelines, that a particular format, protocol or feature of any given technology may be utilized or relied upon in web content when the following conditions have been met: (1) there exist one or more implementations thereof, available under major operating systems (E.G. MacOS, MS-Windows and Unix); (2) these implementations are compatible with assistive technologies; and (3) the implementations are interoperable. For this purpose, only the latest versions of user agents and/or assistive technologies will be considered; if user agents/assistve technologies vary across platforms, only the common features thereof (available on all platforms for which development is ongoing) will be taken into account.
