The macros.txt file attached to Youval's previous post in this thread contains example of freemarker macros. The file content should be passed to the <Macros> trigger as text (you can use Read Resource to load the file contents from the file system, or place your macros in a constant embedded in the model, or any other method you see fit to create the content).
The macros provided can be used in the OpenDocument template passed to through <Template>.
I hope this helps, but if not, please clarify your question (perhaps attaching a model, screenshot and/or opendocument template demonstrating the issue).
For best results, use the Firefox browser..
