Referencing to a class generated in another language/generator Follow

My scenario:

I have a "Document" concept. I defined a generator, which generates classes with names in this form: "class Document{ID}DAO".

In another language, in which I need to have Document{ID}Model which should have "static Document{ID}Model getModel(Document{ID}DAO dao)"

How can I do that? It seems that I have to use some kind of mapping label, but I can't find how to put one on generated class. Besides, it seems that labes are not exported  from one generator to another.
