Unable to use remove statements for the admin menu

[tzyganu]

Let's say that I create a module that should remove a backend menu item. I still don't have a valid use case, but let's say I want that. :).
I see that there is already a menu command for that.
in theory it should work if I add this to my adminhtml/menu.xml file:

<remove id="Dummy_Demo::dummy" />

Doing this throws an exeption:

Missing required param title
#0 MAGENTO_ROOT/app/code/Magento/Backend/Model/Menu/Item.php(184):  Magento\Backend\Model\Menu\Item\Validator->validate(Array)

This happense because the 'title' attribute is marked as required in Magento\Backend\Model\Menu\Item\Validator::$_required. I tried adding a dummy title on the remove command

<remove id="Magento_Catalog::catalog" title="Dummy title" />

But "no go". In this case my xml is not valid, because the remove tag does not support a title attribute, as defined in Magento/Backend/etc/menu.xsd

[EDIT]:

the same goes for the resource attribute and for the <update> command.

Note. It works if I try to remove a core menu, but a non-core one.

Never mind. The problem was ME. Wrong declaration of menu item ids.
