                definitions of message keys specified in the following
                attributes:</p>

                <li><strong>header</strong> - Text that will be rendered
                before the error messages list.  Typically, this message text
                will end with <code>&lt;ul&gt;</code> to start the
                error messages list (default "errors.header").</li>
                <li><strong>footer</strong> - Text that will be rendered
                after the error messages list.  Typically, this message text
                will begin with <code>&lt;/ul&gt;</code> to end the error
                messages list (default "errors.footer").</li>
                <li><strong>prefix</strong> - Text that will be rendered
                before each individual error in the list (default "errors.prefix").</li>
                <li><strong>suffix</strong> - Text that will be rendered
                after each individual error in the list (default "errors.suffix").</li>
