8.2.2 Subelements
Similar to the subelements procedure for metrics (see
Section 8.1.8 "Subelements"), the subelements procedure for sets allows
for a simple way to define a set of all elements that a given model
element contains.
For example, to define the set of all actors in a model, we simply
write:
<set name="ActorSet" domain="model">
<description>The set of actors defined in the model.</description>
<subelements target="actor"/>
</set>
The subelements procedure for sets takes the following, optional,
attributes:
