* Enhances the parent method generateAttributes() by escaping the attribute values.

* array( 'id' => 'my_id', 'name' => 'my_name', 'class' => 'my_class' )
*
* will become
*
* id='my_id' name='my_name' class='my_class'
*
* @since 3.0.0
* @remark The single quotes will be used.
* @remark For an element with an empty string, only the attribute name will be placed. To prevent the attribute name gets inserted, set null to it.
