It is Office 2010. An it is a Capella team project - is this may be a problem?
The template is quite large and worked for quite a long ok except of when this writeMin/MaxCard methods were introduced. Almost identical methods writeMin/MaxValue work ok, though.
I am not able to clone the template: I have created a new Templale (New -> Other -> m2doc Template), copied the contents of our template into it and then I had to set the nsURIs again (I have set all polarsys and sirius ones) and also all the types of the template variables. At the end, when saving it, an error popped up. (It is very tedious to have to set all properties from scratch, therefore I don´t like to do it again. The whole business of nsURIs shoudl be hidden from the user anyway… and there should be a meaningful “copy template” function,)
