 L<Rose::HTML::Form::Field::Email> is a subclass of L<Rose::HTML::Form::Field::Text> that uses L<Email::Valid> to allow only valid email addresses as input.  It overrides the L<validate()|Rose::HTML::Form::Field/validate> method of its parent class, returning true if the L<internal_value()|Rose::HTML::Form::Field/internal_value> is a valid email address, or setting an error message and returning false otherwise.  |

 This is a good example of a custom field class that simply constrains the kinds of inputs that it accepts, but does not inflate/deflate values or aggregate other fields.  |
