Here is what PDE gives me


 <extension
         point="org.eclipse.ui.popupMenus">
      <objectContribution
            adaptable="false"
            id="Scratch.objectContribution1"
            objectClass="scratch.object1">
         <enablement>
            <objectClass name="org.eclipse.core.resources.IFile"/>
         </enablement>
      </objectContribution>
   </extension>
