Sometimes it is desirable to make a copy of a classifier with all its parts, e.g., a device type with all its ports.

copying and pasting diagram elements.

The editor needs to support copy and pasting of model elements.

Need to define a set of goals for the feature which will be achievable. Need to be practical.

• Have option for just copying presentation between diagrams? This should include the layout and configuration of a component implementation into a subcomponent. This aspect isn't necessarily limited to CCP support.
• Copy top level model elements and then just copy presentation for lower elements.
• IDEA: Copying multiple elements: If a connection and other elements are copied, pasting should update the references in the connection(s) to point to the new elements.
