###### Examples:

The following is an example of a logical structure type extension point:

     <extension point="org.eclipse.debug.core.logicalStructureProviders">
      <logicalStructureProvider
       class="com.example.ExampleLogicalStructureProvider"
       modelIdentifier="com.example.debug.model">
      </logicalStructureProvider>
     </extension>

In the example above, the specified logical structure provider will be consulted for alternative logical structures for values from the `com.example.debug.model` debug model as they are displayed in the variables view.
