ティム・バーナーズ=リーによる拡張html提案

ティム・バーナーズ=リーは一気にhtmlをxmlのようなウェル・フォームドのフォーマットに移行させるのは難しいとして、html改良とxhtmlを平行してメンテする新グループの創設を提言する。今までにもW3Cから別れ出たWHAT WGのようなグループがあったが、アカウンタビリティーの点からも問題があった。htmlフォームについても現行のhtmlの上位セットで、かつxformの下位セットであるような拡張htmlを考えている。

The plan is to charter a completely new HTML group. Unlike the previous one, this one will be chartered to do incremental improvements to HTML, as also in parallel xHTML. It will have a different chair and staff contact. It will work on HTML and xHTML together. We have strong support for this group, from many people we have talked to, including browser makers.[...]
there is a work item to look at how HTML forms (existing and extended) can be thought of as XForm equivalents, to allow an easy escalation path. A goal would be to have an HTML forms language which is a superset of the existing HTML language, and a subset of a XForms language wit added HTML compatibility. We will see to what extend this is possible. There will be a new Forms group, and a common task force between it and the HTML group.
