Implementation is just a dummy, though. At first I thought that it
would work to get the XModel of the "current" document (as returned by
getCurrentDocument()), and then get the XFrame of that, and then use
the XFrame's getName() and setName(). But, it seems that
getCurrentDocument() and what it calls is tightly coupled to
StarBasic, and it doesn't do anything sane in the case of Automation
clients.
