This document describes XForms for HTML, which provides a set of attributes and script methods encompassing a useful subset of XForms functionality and mapping that functionality to syntactic constructs that are familiar to authors of HTML and XHTML web pages. The intent of this module is to simplify the means by which web page authors gain access to the rich functionality available from the hybrid execution model of XForms, which combines declarative constructs with event-driven imperative processing. These attributes and script methods increase the initial consumability of XForms by allowing injection of rich semantics directly into the host language markup. In turn, the behaviors of the attributes and script methods are mapped to the XForms model-view-controller-connector architecture so that applications manifest behaviors consistent with having used XForms markup elements. This allows authors to gradually address greater application complexity as it arises in the software lifecycle by opportunistically, i.e. as the need arises, switching from the attributes and script methods of this specification to the corresponding XForms markup elements. This gradual adoption strategy is being further supported by the modularization of XForms into components that can be consumed incrementally by authors and implementers.
