Documents associated with UML® Version 2.0
Release date: July 2005
NOTE: Version 2.0 does not have XSD or XML associated files due to structural problems with the UML metamodel.
Beginning with UML 2.0, the UML Specification was split into two complementary specifications: Infrastructure and Superstructure. The UML infrastructure specification defines the foundational language constructs required for UML 2.0. It is complemented by UML Superstructure, which defines the user level constructs required for UML 2.0. The two complementary specifications constitute a complete specification for the UML 2 modeling language.
