EclipseRCP - Multiple Visible-When CoreExpressions to HandledMenuItem?

Question

In my plugin.xml I have defined multiple restrictions like:

<extension
      point="org.eclipse.core.expressions.definitions">
   <definition id="my.stuff.readAccess1">
      <test>...</test>
   </definition>
   <definition id="my.stuff.readAccess2">
      <test>...</test>
   </definition>
</extension>

In my fragment.e4xmi file I would like to use multiple of these for a simple HandledMenuItem as a Visible-When Expression with a conjuction, is that possible somehow?

My issue is that I have many roles and other restrictions (this menu should be seen only in a specific perspective, etc.), and having to create a CoreExpression for all the menu items one-by-one seems a bit cumbersome.

Any hints if that could be avoided? Thanks in advance!

You can only specify the one core expression, but you can combine other expressions using and and or :

  <definition
        id="my.stuff.readAccess1and2">
       <and>
          <reference
                 definitionId="my.stuff.readAccess1">
          </reference>
          <reference
                 definitionId="my.stuff.readAccess2">
           </reference>
      </and>
  </definition>
