@blissfool, I would suggest a slight restructuring. You can put your basic test (which is correct) in a org.eclipse.core.expressions.definitions block:

<extension point="org.eclipse.core.expressions.definitions">
   <definition id="org.eclipse.example.testExtension">
      <adapt type="org.eclipse.core.resources.IResource">
         <or>
             <test property="org.eclipse.core.resources.extension"
                   value="ext1">
             </test>
             <test property="org.eclipse.core.resources.extension"
                   value="ext2">
             </test>
         </or>
      </adapt>
   </definition>
</extension>

Then in your visibleWhen move the activeEditorInput test up to the top:

<visibleWhen>
   <or>
      <with variable="selection">
         <iterate ifEmtpy="false">
           <reference definitionId="org.eclipse.example.testExtension"/>
         </iterate>
      </with>
      <with variable="activeEditorInput">
        <reference definitionId="org.eclipse.example.testExtension"/>
      </with>
   </or>
</visibleWhen>

You could implement your own PropertyTester.

I was able to get it done with a with variable that I came across. Using the same code example above:

• Add an <or> block within the <iterate> block
• Place the existing <adapt> block in the new <or> block
• Add a new with variable called activeEditorInput

Here is the new code example.

<iterate ifEmpty="false" operator="or">
  <or>
    <adapt type="org.eclipse.core.resources.IResource">
      <or>
        ...test extensions
      </or>
    </adapt>
    <with variable="activeEditorInput">
      <adapt type="org.eclipse.core.resources.IResource">
        <or>
          ...test extensions
        </or>
      </adapt>
    </with>
  </or>
</iterate>
