positive.code: These are JAXB-annotated classes with corresponding XSD schemas; the upshot of that is that IDEs such as IntelliJ and Eclipse can provide "intellisense", making iteasy to author such layout files.
  
  
  [NOTE]
  ====
  It is also possible to describe layouts using a `.layout.json` file.
  However, `.layout.json` support is deprecated; the ``.layout.xml`` file also enables much more sophisticated layouts than those afforded by ``.layout.json``.
  
  If you have an application with older `.layout.json` files, then it is possible to download initial `.layout.xml` files using the xref:../rgsvc/rgsvc.adoc#_rgsvc_metadata-api_LayoutService[`LayoutService`] (exposed as an action on the prototyping menu).
  The `.layout.json` file will be ignored once a `.layout.xml` file is present.

negative.code: * those that defines common components, of: fieldsets (previously called member groups or property groups), properties, collections, actions and also the title/icon of the domain object itself.
