The copy relationship allows you to create a copy that is maintained consistently
with the original. The name and the ID may be different though. The requirement
text is write-protected in the copy and always identical with the original.
The copy relationship is denoted as a dashed arrow pointing from the copy to
the original and with the stereotype ?«copy?» ( Figure 4.11 ).

with the keyword master and the model element to the copy ( Figure 4.12 ).
