[Zope] Zope book error or version difference?

Zope Book .pdf fetched today says on page 258

ObjectManager Constructor

manage_addDocument(id, title)

Add a DTML Document to the current ObjectManager

But when I call manage_addDocument from DTML using in Zope 2.2.2, it actually adds a DTML Method (!) However, manage_addDTMLDocument(id, title) does add a DTML Document. Could be a change between 2.2.2 and 2.3.x or it could be an error in the book, in which case I thought I should point it out. Or maybe I should've skipped the beer with dinner. -- Dennis Nichols nichols@tradingconnections.com
