You can use the mapping table for Component diagram model elements to understand the differences between UML 1.4 and UML 2.0.
UML 1.4 | UML 2.0 |
---|---|
Component | Component Note: All components such as Subprogram Body,
Package Specification, and Task Specifications (stereotyped components) map
to the single UML Component metaclass; however, the UML Component stereotype
identifies them as Subprogram Body, Package Specification, and so on.
