 # CodeBox::CodeAttribute
 
 Lets you define attributes as codes, instead keys (ids). For simple option storage saving a string code is often more simple an conveniant the storing an artificial id-key referencing a special code object.

The localization key is defined in CodeBox (CodeBox.i18n_empty_options_key).

-    * `false` then no empty option is defined (default)
-    * a String then the string is used as label. The value of the option is `nil` by default.
-    * a String starting with `i18n.` the the string is considered as a tranlation key (without the `i18n.` part). Value is nil by default.
-    * is a Hash then the value is take from the Hashs value for key `:value` (nil if not present), and the label is taken from the value of key `:label` (default CodeBox.i18n_empty_option_key). If a String is present it is interpreted as a plain label or I18n key as described above.
