Oops I am sorry .... I do not know whether there is a magic Zope method to
return that. If not then you are right and you will  have to
iterate over all subobjects, like (tested):

<dtml-call "REQUEST.set('tmp',{})">
<dtml-in objectValues>
<dtml-call "REQUEST['tmp'].update({meta_type:''})">
</dtml-in>
<dtml-return "REQUEST['tmp'].keys()">
