XForms-Tiny does indeed run on today's browsers, see
Where you can try it out for yourself on your browser on a wide
range of examples. This makes use of an open source cross browser
script library that works on Internet Explorer 6 and 7, Firefox 1.5,
Firefox 2, Opera 9, Konqueror 3.5, Safari, Opera Mobile 8.6 and
NetFront 3.4. When delivered via HTTP as a compressed file, the
download size is only 6 KBytes. The library will be updated to
reflect changes to the specification, and a first Working Draft is
expected in early 2007.
WF2 has been implemented as a script library for Internet Explorer
and in principle a cross browser library could be developed.
However, web page developers would still need to write additional
page specific scripts to match the features that are built into
XForms-Tiny. For a single page that might be okay but the costs soon
add up when accumulated across applications. A declarative approach
reduces the development cost and likelihood of errors. Another
advantage is the means to automatically generate the server side
validation from the markup rather than having to code it separately
with the risk of mismatch between the client and server code.
p.s. I am looking into providing declarative support for using Ajax to
support dynamic load and save operations without the need for any
additional scripting other than loading the XForms-Tiny library.
