This key is used to define parameters related to formatting error messages
returned to the user.

By default, invalid fields have the message "Invalid" associated with them
while missing fields have the message "Missing" associated with them.

In the simplest case, nothing needs to be defined here, and the default values
will be used.

The default formatting applied is designed for display in an XHTML web page.
That formatting is as followings:

    <span style="color:red;font-weight:bold" class="dfv_errors">* %s</span>

The C<%s> will be replaced with the message. The effect is that the message
will appear in bold red with an asterisk before it. This style can be overridden by simply
defining "dfv_errors" appropriately in a style sheet, or by providing a new format string.

Here's a more complex example that shows how to provide your own default message strings, as well
as providing custom messages per field, and handling multiple constraints:
