The Applet Deletion Manager need not be implemented as an applet on the card. The requirement is only that the Applet Deletion Manager functionality be SELECTable. The corollary to this requirement is that Applet Deletion Manager component shall not be able to be invoked on a logical channel where a non-Applet Deletion Manager applet is an active applet instance, nor when no applet is active.

A Java Card RE implementer could choose to implement the Applet Deletion Manager as an applet. If so, the Applet Deletion Manager might be coded to extend the Applet class and to respond to invocations of the select, process, and deselect methods, and, if necessary, the methods of the javacard.framework.MultiSelectable interface.

However, a Java Card RE implementer could also implement the Applet Deletion Manager in other ways, as long as it provides the SELECTable behavior to the outside world. In this case, the Java Card RE implementer has the freedom to provide some other mechanism by which APDUs are delivered to the Applet Deletion Manager code module.
