+</span> * @class Ext.form.field.Field
+
+This mixin provides a common interface for the logical behavior and state of form fields, including:
+
+- Getter and setter methods for field values
+- Events and methods for tracking value and validity changes
+- Methods for triggering validation
+
+**NOTE**: When implementing custom fields, it is most likely that you will want to extend the {@link Ext.form.field.Base}
+component class rather than using this mixin directly, as BaseField contains additional logic for generating an
+actual DOM complete with {@link Ext.form.Labelable label and error message} display and a form input field,
+plus methods that bind the Field value getters and setters to the input field's value.
+
+If you do want to implement this mixin directly and don't want to extend {@link Ext.form.field.Base}, then
+you will most likely want to override the following methods with custom implementations: {@link #getValue},
+{@link #setValue}, and {@link #getErrors}. Other methods may be overridden as needed but their base
+implementations should be sufficient for common cases. You will also need to make sure that {@link #initField}
+is called during the component's initialization.
