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?

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?

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.

I am not convinced yet. :)

OK. But that doesn't answer my question.

No. It isn't clear to me.

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.
