XForms

XForms is an XML format for the specification of a data processing model for XML data and user interface(s) for the XML data, such as web forms. XForms was designed to be the next generation of HTML / XHTML forms, but is generic enough that it can also be used in a standalone manner or with presentation languages other than XHTML to describe a user interface and a set of common data manipulation tasks.

XForms, much like XHTML 2.0 which is currently under development as of November 2006 and within which XForms will be embedded, differs from previous versions of XHTML. Because of this there is a learning curve for developers, but because XForms in general provides a large time savings for the development of enterprise quality web forms, it can be an attractive alternative for many uses.
XForms 1.0 (Third Edition) was made an official W3C Recommendation on 29th October 2007.

XForms 1.1, which introduces a number of improvements, was made an official W3C Recommendation on 29th November 2007.
