Handling of existing UML Models

[JDziurlaj]

I have an existing structural model (i.e. a class data model) that I want to use with my Alf models. Can the Alf reference implementation interpret a structural model in XMI, or will I need to reverse engineer it into Alf? From what I can tell, the Alf tooling expects that structural model to be defined in Alf as well.

I won't want this class model to become part of the eventual output (via alfc, however, only referenced (I assume this is what @ModelLibrary means?).
