Description Koen Staal CLA 2017-05-04 02:03:01 EDT 
When working with Xtext and Sirius it is helpfull to have an overview of the diagrams inside the aird file, but not show the contents of the semantic model files. 
Sirius Content Management also shows the contents of Xtext DSL files which is unnecessary and maybe confusing for the DSL users. 
For example see slide 13 of https://www.slideshare.net/Obeo_corp/siriuscon2016-integrating-textual-and-graphical-editing-in-the-poosl-ide. This could be solved by a Common Navigator filter.

Thanks for your detailed enhancement submit.

Nevertheless, we have currently not planned to work on it in the following releases.

But you can provide your own filter by using something like:

   <extension
         point="org.eclipse.ui.navigator.navigatorContent">
      <commonFilter
            activeByDefault="false"
            class="myPackage.MyViewerFilter"
            id="test.myFilter"
            name="My filter"
            visibleInUI="true">
      </commonFilter>
   </extension>
   <extension
         point="org.eclipse.ui.navigator.viewer">
     <viewerContentBinding
           viewerId="org.eclipse.sirius.ui.tools.views.model.explorer">
        <includes>
        <contentExtension pattern="test.*"/>
        </includes>
     </viewerContentBinding>
   </extension>

Thanks for your suggestion. 
However there are 2 problems with this solution. It hides the error/warning decorator on the file, we made a bug report of this a while back: https://bugs.eclipse.org/bugs/show_bug.cgi?id=454424 

The file will still have the expandable indicator (little triangle) infront of the model file until eclipse actually tries to expand it. Only then the filter gets applied and the triangle dissapears (because there is nothing to show)
