	<li><tt>name</tt>: The name of the copy</li>
</ul>
</p>

	<li><tt>name</tt>: The name of the new attribute</li>
	<li><tt>type</tt>: The type of the new attribute</li>
	<li><tt>lowerBound</tt>: The lower bound of the new attribute</li>
	<li><tt>upperBound</tt>: The upper bound of the new reference</li>
	<li><tt>defaultValue</tt>: The default value literal</li>
</ul>
</p>



<h2 id="newClass">Create Class</h2>
<p>
In the metamodel, a new class is created. Nothing is changed in the model.
</p>

<p><h5>Parameters:</h5>
<ul>

	<li><tt>name</tt>: The name of the new class</li>
	<li><tt>superClasses</tt>: The super classes of the new class</li>
	<li><tt>abstr</tt>: Whether the class is abstract</li>
</ul>
</p>



<h2 id="createEnumeration">Create Enumeration</h2>
<p>
In the metamodel, an enumeration is created. In the model, nothing needs to be changed.
</p>

	<li><tt>literals</tt>: The names of the literals of the new enumeration</li>
</ul>
</p>



<h2 id="newGMFConstraint">Create GMF Constraint</h2>
<p>
In the metamodel, a new constraint is introduced. Nothing is changed in the model.
</p>

<p><h5>Parameters:</h5>
<ul>

</p>

<p>
<h5>Constraints:</h5>
<ul>
	<li>The element must not be an annotation.</li>
</ul>
</p>


<h2 id="newOppositeReference">Create Opposite Reference</h2>
<p>
In the metamodel, an opposite is created for a reference. In the model, the opposite direction needs to be set.
</p>
