Annotation s are mapped next. Note that we'll again use the “phantom
node” concept here because the annotation link determines the archetype that
will contain the annotation. Although it's possible to attach annotations to every
model element, we provide for only archetype annotations at this time. Some
complications arise when attaching links to compartment items. Table 4-40
shows the Annotation node and link mappings.

Now we return to the Association link that the wizard created. Complete
the mapping as shown in Table 4-41, taking note of the initialization of our ele-
ment, including a Java initializer that we'll need to provide code for later.
