I am using the ETP 1.1 to create a ETP application like news, faq etc.
Here's what I did:
1. mount ETP on http://mysite/book
2. set up in the parameters of this instance the appropriate variable so it uses the docbook template.
3. When you go to book , it asks for title,preface, author, copyright,
4. I have definitions for chapter, section or secsection
They all have attributes title, description, para, subpara.
These are content items.
Hope I made it clear
