I have similair worries, in my particular instance (financial data
gathering) - I am trying to absolutely minimize the amount of logic and
layout in the xforms/xhtml pages. 

One way I'm thinking of approaching this is to do away with
select1/select/etc - and use only the <input/> element - with the
display of the field entirely dependent on the datatype of the ref'd
data - and the appearance attribute. Eg - enumerated datatypes are
listed as a (dropdown|checkboxes) - depending on the appearance

I do data-type constraints at xforms-deactivate time, and validation for
the included inputs (only !null at this stage) at xforms-submit time.

I'm very new to xforms and xml and haven't had time to totally get my
head around the best way to do things - but I think tying a lot more
functionality back to schemas (and possible a new form of schema that
isn't so bloody hard to parse) would make xforms more applicable to
real-world situations.

I fear xforms will rapidly degenerate into a cross-browser javascript
type mess otherwise.

I guess ease of maintenance is a little in the eye of the beholder.

As I work with XForms-containing code it seems to me that XForms, with
binding between different parts of the code and the potential for 
event-processing code to be widely separated in large pages, has the 
potential to create many maintenance difficulties.

It reminds me of the tangle that early forms of JavaServer pages could 
produce once they moved beyond the trivial. Obviously the issues aren't 

It seems to me that XForms has similar potential to be less than easy to


Have others been considering this issue? Any thoughts about approaches
can minimise the likely problems?
