First of all thanks to everybody for chipping in and commenting on my problem.

The most interesting case (which we have had in the past) is the addition of a field that is linked to functionality which can optionally be used by the member. It would be great if a member would not be forced to update the template and simply ignore the new field(s). This is the only way he can avoid retesting of his application. If the member needs the new functionality, he has to test this anyway and then a new template is not an issue.

For more complex changes such as field deletions, operator changes, data type changes, I do not see an actual benefit in terms of being able to skip re-testing.

Regards,
Hanno.
