I'm switching my generator over from using weaving rules to using reduction rules. When I used weaving rules, I was able to have multiple template fragments in a ClassConcept referenced by my root mapping rule. Now that I've switched to reduction rules, I get an error stating that I have more than one template fragment. Each fragment is the body of separate methods in the class. What is the recommended approach when you need to emit into a class multiple method bodies utilizing the same model fragment for each?
