   The attached `Classification` objects are shown in two contexts: as a table of `Classification` objects for the
  -"classified" domain object, and then as the actual subtype when the alias object itself is shown (eg
  +"classified" domain object, and then as the actual subtype when the classification object itself is shown (eg
   `ClassificationForDemoObject` in the demo app).
   
   In the former case (as a table) the `Classification` will be rendered according to the `Classification.layout.xml`
  
positive.code: `Classification.CssClassSubscriber`.  The consuming module can override these values simply by providing alternative
  implementations.
  
  [TIP]
  ====
  The (non-ASF) http://github.com/incodehq/incode-module-alias[Incode alias] module also allows the title/icon/CSS class to be overridden; its example application includes an example to demonstrate how this is done.
