Andrew,
 
I have to agree with you that model used by Infopath is quite useful.
 
Besides legal/security issues, I would classify 'forms' market into
enterprise and internet. Standards compliance is necessary for internet
class of applications. For enterprise apps, the focus is more on business
logic, workflows, end-user conveniences, efficient manipulation of remote
and local data, multiple views of the same data, compatibility with other
applications such emails, word processing, etc. In other words, rich client
functionality is desirable. 
 
There is an overlap between the two, but, as it stands now, I don't believe
XForms completely qualify being a rich client (although its a smart
client!). Comparing the two, Infopath styled applications may be more
suitable for enterprises. However, the principles embodied in XForms could
be (and might have been used in Infopath) used in wider context and not only
limited to browsers.

Mark,

I notice that you didn't respond to my point:

>How does the UK insurance industry propose to handle the types of legal
issue which >John Messing mentioned in the "How secure is XForms?" thread?

Am I correct in assuming that your old system didn't cover that nor does the
new? Do legal requirements in the UK and USA differ?

>Why?

E.g. A form will be authored by company X, and perhaps deployed by them on
one or two of their own channels. The form will also be deployed by three
third parties for use by potentially thousands of end users, some of whom
work in organisation with a sophisticated IT infrastructure, while others
have a telephone and fax machine. The form cannot be reauthored in any way.




Um .... not being facetious ... but how do you get the XML instance data
down the phone line or in the fax? It seems to me that some form (forgive
the pun) of refactoring is going on anyway. So, in principle, why not
InfoPath too?




Key points are:

1) The form author does not know how the form is to be deployed at authoring
time
2) Many organisations will host the same form, providing access to end users
with many different delivery requirments.




Ah ... but what is a "form"? It's a serious question. One the XForms WG
ducked ... shame on them! :) ... and leaves terminology in a flakey state.

If you have a set of form controls on an electronic XForms form and have a
set of similar looking (but non-functioning) widgets on a paper form is that
the "same form"? Or not? It isn't obvious to me. Is the paper form an XForms
form?

I must make a point of seeing how T V Raman handles the issue of "what is a
form?" in his book as I continue reading it. I guess the overview format
allows avoidance of practical little issues like that. "Form" doesn't make
it in the index.



It turned out to be cheaper and more practical to produce our own forms
markup language than to leave all form generators and users to do their own
thing.

Yes.



I am not convinced yet. :)

For us XForms addresses forms/business rules deployment across organisations
that have contractually regulated relationships. 



OK. But that doesn't answer my question.

Hopefully that should be clear from comments above.




No. It isn't clear to me.



>Does your industry's application require that the visible "form" of 
>the form is common? Or that the XML data submitted is?

Both or either depending on circumstances. 



So if InfoPath could submit identical to XForms that would be ok in some
circumstances?

Then there is the matter of the business rules underlying a form.






What do you mean by business rules in this context?

I am challenging your proposition of this type of decision being simple and
the assertion that "standards" are "all there is to it". I simply am not
convinced that it is "that simple".

The assessment of your needs is yours and the decision on a chosen solution
likewise. I do find it difficult to see how this is as simple as you
indicate.
