Hi, At 05:00 30/10/2005, Gregg Vanderheiden wrote: <blockquote> I just noticed the definition of user agent in our guidelines (...) 1. The software and documentation components that together, conform to the requirements of the User Agent Accessibility Guidelines 1.0 (UAAG 1.0). This is the most common use of the term in this document and is the usage in the UAAG checkpoints. 2. Any software that retrieves and renders Web content for users. This may include Web browsers, media players, plug-ins, and other programs including assistive technologies that help in retrieving and rendering Web content. (...) Isn’t the second definition the one we mean most? Not the first? In fact isn’t the second definition the only thing we mean by the term user agent? </blockquote> In my opinion, we can only use the second definition. We can't safely assume that user agents conform to UAAG: for some technologies, the user agent is not something that is installed on a device controlled by the user. For VoiceXML applications, the user agent is the VoiceXML processor [1] or the "VoiceXML interpreter context" [2]. This is software that is installed on a machine that a user accesses by telephone. It acts upon events caused by user action (e.g. spoken or character input, disconnect, ...) and retrieves files from a document server (e.g. a Web server) when necessary.
