Creating a profile package for lightweight extensions
1. Right-click the Model, and select New > Package.
2. Type the name of Package, and then press the Enter key. The name of each profile Package in a model must be unique.
The name you type (with the text 'Profile' or 'Extensions' removed) will appear as a subfolder in selection dialogs.
3. Open the Package's Property Pages.
4. Click the Options tab.
5. Select the Profile Package check box.
6. Right-click the Package, and select Links > Stereotypes > LightweightProfile.
You can create Packages within your profile Package to organize any items you create. If you create sub-Packages, do not apply the «LightweightProfile» stereotype to those sub-Packages, and do not select the Profile check box for those sub-Packages.
