1) If a contribution doesn't have sca-contribution.xml for the exports, all the artifacts should be private to the contribution (similar as an OSGi bundle that doesn't export any packages). We can only use it by attaching a deployment composite. I don't think we should change the visibility.
2) The SCA spec doesn't allow duplicate component names within the domain. If two contributions both contain deployable composites that have name conflicts. That's an error. Why does Tuscany try to allow that?
