* Stores errors and a list of child element errors directly on each element.

* opened when child elements have errors.
*
* Grouping example:
* Assume you have a 'street' element somewhere in a form, which is displayed
* in a details element 'address'. It might be:
* @code
* $form['street'] = [
* '#type' => 'textfield',
* '#title' => $this->t('Street'),

* '#required' => TRUE,
* ];
* $form['address'] = [
* '#type' => 'details',
* '#title' => $this->t('Address'),
* ];
* @endcode
*
* When submitting an empty street field, the generated error is available to
* the different render elements like so:
* @code
* // The street textfield element.
* $element = [
* '#errors' => {Drupal\Core\StringTranslation\TranslatableMarkup},
* '#children_errors' => [],
* ];
* // The address detail element.
* $element = [
* '#errors' => null,
* '#children_errors' => [
* 'street' => {Drupal\Core\StringTranslation\TranslatableMarkup}
* ],
* ];
* @endcode
*
* The list of child element errors of an element is an associative array. A
* child element error is keyed with the #array_parents value of the
* respective element. The key is formed by imploding this value with '][' as
* glue. For example, a value ['contact_info', 'name'] becomes
* 'contact_info][name'.
*
* @param array $form
* An associative array containing a reference to the complete structure of
* the form.
* @param \Drupal\Core\Form\FormStateInterface $form_state
* The current state of the form.
* @param array $elements
* An associative array containing the part of the form structure that will
* be processed while traversing up the tree. For recursion only; leave
* empty when calling this method.
