implements RepositoryItem, MutableRepositoryItem

This class includes only the external ID property plus the list of properties in a RepositoryItem that have been changed. When, for example, updateItem is invoked on an IntegrationRepositoryItem, this wrapper can be passed to the update Command instead of the RepositoryItem. This allows us to send only the changed properties to be saved to the remote system, instead of trying to update all the properties of a repository item.

For example, if you change the middleName property of the user profile, and the user profile is configured with an external id property called remoteId, the ChangedPropertyBean will only expose two properties: middleName and remoteId. If you call ChangedPropertyBean.getPropertyDescriptors, the result will only contain these two properties. A ChangedPropertyBean is read-only.
