Hi Dave,
Thanks for the update. Given that XF-T has already proven to run on today's
browsers, no matter how the W3C ends up reconciling XF-T vs WF2, it seems
to me that a MUST requirement is that the result of this XF-T vs WF2
reconciliation should be technology that can be implemented via a small
JavaScript library such that it can run on top of today's browsers.

It would also be nice if:

1) There was a highly modular open source implementation of this new (XF-T
vs WF2) technology which could be added as a module to the many fine Ajax
libraries that exist in the world.
2) There was some attention to make sure that this new (XF-T vs WF2)
technology were designed to integrate well with HTML/Ajax IDEs so that
developers can create and debug their applications using modern software
development approaches, such as WYSIWYG developer tools and integrated

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.
