Class UML 2.3::Component
Description:
In the namespace of a component, all model elements that are involved in
or related to its definition are either owned or imported explicitly. This
may include, for example, use cases and dependencies (e.g. mappings), packages,
components, and artifacts.

is an implementation.

ElementConstraints:
Signature: no_packaged_elements() : Boolean;
Description: component nested in a Class cannot have any packaged elements.
Expression: (not self.class->isEmpty()) implies self.packagedElement->isEmpty()
Signature: no_nested_classifiers() : Boolean;
Description: A component cannot nest classifiers.
Expression: self.nestedClassifier->isEmpty()
Operations:
