XForms 1.1

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 underlying data of a form is organized into instances of data schema (though formal schema definitions are not required). An XForm allows processing of data to occur using three mechanisms: (1) A declarative model composed of formulae for data calculations and constraints, data type and other property declarations, and data submission parameters. (2) A view layer composed of intent-based user interface controls. (3) An imperative controller for orchestrating data manipulations, interactions between the model and view layers, and data submissions. Thus, XForms accommodates form component reuse, fosters strong data type validation, eliminates unnecessary round-trips to the server, offers device independence and reduces the need for scripting. XForms 1.1 refines the XML processing platform introduced by XForms 1.0 by adding several new submission capabilities, action handlers, utility functions, user interface improvements, and helpful datatypes as well as a more powerful action processing facility, including conditional, iterated and background execution, the ability to manipulate data arbitrarily and to access event context information.
