HTML and CSS Reference
of forms, known as XForms, is currently a "working document," subject
to review and changes as needed. XForms differs from the conventional
forms model in almost every way: the forms are defined differently,
data is validated differently, and information is transmitted to the server
differently. As you might imagine, XForms is not currently supported
by any browser or server, although a preliminary version of XForms is
available for testing as part of the Mozilla XForms Project. Given its lack
of general support, dramatic differences from the current model, and
the long odds that XForms will replace the millions of forms already in
use, it would be premature to address it in any detail in this chapter.
Instead, we'll cover the forms as defined in HTML and XHTML, and leave
you with a warning that a new forms model may be coming at some
point in the future.
