Adding the Simulink profile to a model (Integration for MATLAB Simulink)
* 
Do not make changes to the Simulink profile. Any changes you make will be lost when the profile is updated.
* 
You can create Tag Definitions outside of the Simulink profile, and link those Tag Definitions to Stereotypes in the Simulink profile. When the Simulink profile is updated, the links will not be broken.
Do not create copies of the Simulink profile within a model, or create copies of the Simulink profile through XMI Import/Export. The copies of the Simulink profile will not work correctly and you will not be able to update the copies through the Update All Profiles command.
The Simulink Profile makes use of SysML items in a model, for which you require the SysML Profile.
