I agree, and it would be good if this was recorded as a requirement 
somewhere. For SPIN this could be another triple such as 
spin:violationLevel spin:Warning (or similar). We have encountered this 
as a requirement many times - some input errors are acceptable to at 
least click OK, and fix it later.

Another related use case is that if a constraint violation happens, the 
system could *suggest* a fix. In SPIN we do this by creating 
INSERT/DELETE template calls as part of a constructed 
spin:ConstraintViolation. This can be exposed by user interfaces via a 
button "Fix me".
