P&T Contacform plugin: what's the use of the errors if fields are not required? In the Contactform plugin page there's a code example that's confusing me.

Only the email and message are required in the code, but the fromName field does have an error syntax:

&lt;input id="fromName" type="text" name="fromName" value="{% if message is defined %}{{ message.fromName }}{% endif %}"&gt;
{{ message is defined and message ? errorList(message.getErrors('fromName')) }}


What's the use of the getErrors here? I've tried using rare characters, but no errors?
In the ContactFormModel you can manage the attribute 'required' => true.

The example just show how to use the getErrors for each field.

You can delete the ones you dont need.
