Package dialog box
Packages
A package is a general purpose mechanism used to organize elements into groups of model elements and diagrams. Packages can contain other packages.
The "Package" dialog box contains four tabs - "Properties", "Notes", "Tagged values" and "Stereotypes". For information on these standard dialog box tabs, please see "Standard dialog box tabs".
