The Embed- base class is parent to other classes that, by design, are never to be used as top-level structures.

By definition, a class derived from the Embed- base class is used only for embedded, rather than top-level, clipboard pages. Accordingly, no saved instances of concrete Embed- classes ever exist.

In many situations, the choice between creating a new Embed- class and a new Data- class is arbitrary. By choosing an Embed- class, developers record their intention that the class is never to be used for (top-level) pages or saved objects.

Developers can create rules that apply to embedded instances, which execute on the clipboard instances of the Embed- class, but the embedded instance is never saved, or is saved only as a page within another object. For example, the standard decision tree rule Embed-Warning.ShowWarningOnForm applies to instances of the Embed-Warning class, which hold warnings associated with rules.
