<p class=MsoPlainText><font size=2 face="Courier New"><span style='font-size:
10.0pt'>GME provides a light-weight mechanism for extending modeling languages
called GME Type Inheritance. It’s a way of treating domain model
artifacts as types. You can then instantiate or subtype those types.<o:p></o:p></span></font></p>

<p class=MsoPlainText><font size=2 face="Courier New"><span style='font-size:
10.0pt'>To continue in the example you provided, you could use the low-level
signal flow concepts from P1 to design discrete components for each of the more
complex guitar effects you would like to see in P2. Then, you could treat each
of those components as a new type belonging to P1. You don’t actually
build a new modeling language, you simply add higher-level reusable modeling constructs
to your old one.<o:p></o:p></span></font></p>
