[Dovecot] Setting up mixed mbox and maildir

[Jonathan Ryshpan]

I'm trying to set up a dovecot server for which mail arrives in an mbox,
and mail is stored in a maildir.  The wiki (see
http://wiki.dovecot.org/Namespaces) refers to this as "Mixed mbox and
Maildir".  It advises handling this situation by creating two
namespaces: one for the mbox and the other for the maildir. Each of 
these namespaces starts with
	namespace private {

On the other hand the sample configuration in the documentation puts
inbox in a namespace starting with:
        namespace inbox {
          # Namespace type: private, shared or public
          #type = private

It appears that there has been a change in the configuration syntax
after the wiki was written, and that the word following namespace 
no longer gives a property of the namespace, but rather its name.  
Is this correct?  In any case, how should the configuration be modified
to handle mixed mailboxes?
