Hi Cat,
I've had a look at the Document Templates in the Resources Window and confirmed that my new .rtf templates appear in that list, so I can confirm that these are the same thing that we're talking about.
The templates contain the "instructions" that create the .rtf document when you run the .rtf report generator (F8).
Looking at your more detailed questions...
[a]Where does the fixed content come from - is it standard corporate logo and speel type data?
I started with a word document that has been set up with all of the corporate style etc. in it. The document contains the corporate logo, table of contents, distribution, headings, footers etc.
[c]No, not sure. What? How?
For each thing I want to appear in the final word document, lets say in this case the Use Case diagram... You apply the following steps.
1. Right Click the item in the Project Browser.
2. Select "Copy rtf bookmark"
3. Switch back to your word document.
4. Place the cursor where you want the diagram to appear.
5. Select Insert | File
6. Navigate to your intended .rtf (intermediary) file
7. Single click on the .rtf file name
8. Click on the range button in the same window
9. Paste (Ctrl-V) the bookmark into range field in the Set Range dialog
10. Click Insert.
If you have already generated the .rtf file that contains the bookmark, the content will now magically appear in your word document.
To generate the .rtf that contains the Use Case Diagram, you would have selected the package that contains the diagram (or the diagram itself) and generated a .rtf file using the Use Case template.
The basic and alternative flows come together as a package if you follow these steps and copy the .rtf bookmark for the Use Case itself (the bubble, not the bubble diagram).
You can't copy a .rtf bookmark for the glossary, so in that case, I generate a stand alone glossary report, and add a link to that .rtf file.
Hopefully this is helping...
