where for example valid postal codes vary by country, if the validation 
were to be done only from the back end, would this mean every country 
would need its own version of the table field constraints? Is that in 
fact the easiest way to accommodate such differences?

or at least, to be *able* to have allocated to them the character 
types...

Presumably a "smart date" function, which would interpret a single 
integer as the date of the current month etc, would operate in a client 
widget rather than via the back end? The back end would only care that 
it is a valid date and, for example in the case of a date of birth, 
must not be a date in the future?

Back in my old FoxBASE application -- which I still use for billing -- 
field formatting support included

! to make all alpha characters upper case
9 to specify a character that must be an integer
A to specify a character that must be a-z, A-Z
X to specify a character that must be a-z, A-Z or an integer
(others...)

is this something for which there is built-in support in 
wxpython/wxwidgits?
