+/**
+ * A mixin which allows a component to be configured and decorated with a label and/or error message as is
+ * common for form fields. This is used by e.g. Ext.form.field.Base and Ext.form.FieldContainer
+ * to let them be managed by the Field layout.
+ *
+ * NOTE: This mixin is mainly for internal library use and most users should not need to use it directly. It
+ * is more likely you will want to use one of the component classes that import this mixin, such as
+ * Ext.form.field.Base or Ext.form.FieldContainer.
+ *
+ * Use of this mixin does not make a component a field in the logical sense, meaning it does not provide any
+ * logic or state related to values or validation; that is handled by the related Ext.form.field.Field
+ * mixin. These two mixins may be used separately (for example Ext.form.FieldContainer is Labelable but not a
+ * Field), or in combination (for example Ext.form.field.Base implements both and has logic for connecting the
+ * two.)
+ *
+ * Component classes which use this mixin should use the Field layout
+ * or a derivation thereof to properly size and position the label and message according to the component config.
+ * They must also call the {@link #initLabelable} method during component initialization to ensure the mixin gets
+ * set up correctly.
