Uninstallation Implications for the <createDependency> Step

A component cannot be uninstalled if installed components depend on it. When an uninstall block of a component is encountered, if one or more persistent dependencies exist for which the component is the dependee, the uninstallation fails immediately.

However, if component B is being uninstalled by another component A, dependencies created by A on B will not prevent B from being uninstalled, and will be implicitly removed when B is successfully uninstalled.

The dependee component can specify actions to uninstall its dependents by using a <dependantCleanup> block.
