Part 3 - Behavioral Elements
1. In 2.8: typo "that is used to model proocesses." Should be
"processes"
2. In 2.9.2, Figure 2-15: "Clas" should be "Class"
3. In 2.9.2, Figure 2-15 and Argument: There is an internal
inconsistency. The relationship from Argument to Action is diagrammed as a
composition. The text says: [An argument] "is aggregated within an action."
Is it aggregation or composition?
4. Continuing #3: Also the glossary definition of composition ties
non-fixed multiplicity and coincident lifetimes. Does 0..1 count as
non-fixed? If so, where is it defined? What does this distinction mean in
the first place?
5. In 2.9.2, Instance: "The instance construct defines an entity to
which a set of operations can be applied ..." Operation should be method.
Operations exist at the Classifier level; methods are instances of
operations and exist at the instance (application) level.
6. In 2.9.2, Instance\Tagged Values\persistent: "Persistence denotes
the permanence of the state of the instance, marking it as transitory (its
state is destroyed when the instance is destroyed) or persistent (its state
is not destroyed when the instance is destroyed)." Seems it should say that
transitory is the default. Else add transitory as a tagged value.
7. In 2.9.2, Figure 2-16: Would two refinements be clearer than the two
associations from Link to Association and LinkEnd to AssociationEnd since
they are a different levels of abstraction? Also from Instance to
Classifier? [Should the relationship from Method to Operation in 2.5.2,
Figure 2-5 also be a refinement?]
8. In 2.9.2, Figure 2-16: Should the composition relationship from
Attribute to Classifier also be modeled?
9. In 2.9.2, Figure 2-16: The element Instance is abstract according to
the text and should be stereotyped <<abstract>>.
10. In 2.9.2, Link: "In the metamodel Link is an instance of an
Association. It has a set of LinkEnds that matches the set of
AssociationEnds of the Association." In Figure 2-16 LinkEnd to Link is

. Should this be consistent with AssociationEnd to Association?
