Forms were introduced into HTML in 1993. Since then they have become a critical part of the Web. The existing mechanisms in HTML for forms are now outdated, and W3C has started work on developing an effective replacement. This document outlines the requirements for "XForms", W3C's name for the next generation of Web forms.
This section describes the status of this document at the time of its publication. Other documents may supersede this document. The latest status of this document series is maintained at the W3C.
This is a Working Draft that incorporates new material agreed upon at the Boston face to face meeting, including the adoption of XML Schema replacing XForms Simple Syntax, as well as initial efforts at modularizing XForms and additional feedback from outside sources. Interested parties are encouraged to provide additional feedback and comments.
This document is a W3C Working Draft for review by W3C members and other interested parties. It is a draft document and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use W3C Working Drafts as reference material or to cite them as other than "work in progress". A list of current public W3C Working Drafts can be found at http://www.w3.org/TR.
