When a stereotype has many properties, it is very useful to group these properties into named groups. For this purpose, every property could have a tagged value with its group name.

To group tags

1. Open the Specification window of the stereotype property.
2. Click the Tags property group.
3. Select the groupName property and assign a value for it:
   1. Click the Edit Value button
   2. In the Value  area, type a group name.
      
      .
4. Repeat these steps for every stereotype property.
