The W3C is active in this area, particularly through the device-independence working group which has drafted principles that are consistent with, but more elaborate than, those of our requirements document in this respect. See http://www.w3.org/TR/di-princ/ The general model is one in which a user agent requests a web page designated by a device-independent URI, and there is an adaptation process which ensures that the delivered content is appropriate to the environment in which it is to be presented, including the user's needs and preferences. This environment is termed the "delivery context" and includes the access mechanism (i.e. the user agent), user preferences, network band width and other relevant factors. Also germane to our discussions is the distinction which the device-independence principles draw between a "functional presentation" and a "customized presentation". The former is sufficient to enable the user to carry out the task or achieve the purpose for which the site was developed, as envisaged by the author. The latter is a presentation which satisfies the author's quality criteria with respect to a given delivery context. Full details of these concepts are provided in the document itself, which I would recommend reading.
