         This extension point is used to register QVT execution engine. A QVT execution engine provides an implementation of the  &lt;code&gt;org.eclipse.qvt.declarative.execution.ExecutionProvider.execute&lt;/code&gt; method which is able to execute the transformation. To do so, it may rely on a compiler to having produced files containing a description of the instructions to perform (see &lt;code&gt;org.eclipse.qvt.declarative.compilation.ide&lt;/code&gt;).

         Following is an example of how execution engine can be registered:
&lt;pre&gt;
	&lt;extension point=&quot;org.eclipse.qvt.declarative.execution.ide.executionProvider&quot;&gt;
      &lt;executionProvider
            class=&quot;com.example.MyExecutionEngine&quot;
            priority=&quot;low&quot;&gt;
      &lt;/executionProvider&gt;
   &lt;/extension&gt;
&lt;/pre&gt;
      </documentation>
   </annotation>

   <annotation>
      <appinfo>
         <meta.section type="apiinfo"/>
      </appinfo>
      <documentation>
         The value of the &lt;tt&gt;class&lt;/tt&gt; attribute must be the qualified name of an extension of the &lt;tt&gt;org.eclipse.qvt.declarative.execution.ExecutionProvider&lt;/tt&gt; class, that provides a constructor without any arguments.

The value of the &lt;tt&gt;priority&lt;/tt&gt; attribute must be a string either lowest, low, normal, high, highest describing an ordering on providers.
