Extension
Extension is used when modeling a profile to extend SysML (or UML).
Extension is a kind of Association. One end of the Extension is an ordinary Property and the other end is an ExtensionEnd. The former ties the Extension to a (meta)Class, while the latter ties the Extension to a Stereotype that extends the Class.
The steps to use the Extension definition to create an extension are described in Association End to Stereotype as ExtensionEnd.
