XForms is an XML application that represents the next generation of forms for the Web. XForms is not a free-standing document type, but is intended to be integrated into other markup languages, such as XHTML, ODF or SVG. An XForms-based web form gathers and processes XML data using an architecture that separates presentation, purpose and content.

The forms have been also improved in HTML5 standard , although i dont expect HTML 5 to be released officially till 2010 end or may be more time.
