[Zope] How to get title of a DTML Document?

Sorry if this is a basic newbie question, but I've sifted through the docs and haven't been able to find the answer. I've got a document that I include in my standard_html_header. That works fine. But I'd like to also use the DTML Document's title in the header. I've hacked away at dozens of different possibilities, and none of them have worked. Any hints? Thanks in advance for any help.
