[Zope3-dev] Why does the following browser configuration fail?

[Morten W. Petersen]

Hi,

I have the following browser configuration:

<configure
         xmlns="http://namespaces.zope.org/zope"
         xmlns:browser="http://namespaces.zope.org/browser"
 >

   <browser:addMenuItem
         title="Recipe"
         class="worldcookery.recipe.Recipe"
         permission="zope.ManageContent"
         view="AddRecipe.html"
   />

<!--
   <browser:addform
         schema="worldcookery.interfaces.IRecipe"
         content_factory="worldcookery.recipe.Recipe"
         label="Add Recipe"
         name="AddRecipe.html"
         permission="zope.ManageContent"
   />

   <browser:editform
         schema="worldcookery.interfaces.IRecipe"
         label="Edit"
         name="edit.html"
         menu="zmi_views" title="Edit"
         permission="zope.ManageContent"
   />
-->

</configure>

which fails when the two last options are commented out, but works fine 
when none are commented out.  Is there a reason why it fails when the 
two last .. directives are commented out?
