Given a file is selected using the fileselect component
And one or more of the restrictions bound to the control are violated
The error message that is displayed should be configurable
For example, if the maxFileSize restriction has been set to 20mb and a file larger than that is selected, the control currently displays some error text to the user as follows: "File size too large". It would be beneficial if we could override this message so it (for example) could say "File size too large. The maximum file size is 20mb".
