Parameter Tagged Values

Behavioral parameters can have Tagged Values associated with them. Tagged Values offer a convenient extension mechanism for UML elements; you can define any tags you like and then assign values to them using this form.

Tagged Values are written to the XMI output, and can be input to other third party tools for code generation or other activities.


Tagged Values are supported for attributes, operations, objects and connectors.
