This may be a very stupid question but how do I find out what @Managed Types are available for the new Model configuration?

I see lots of references to `ModelMap<Task>` and notes that `org.gradle.api.Task` implements `ModelMap` but I don’t see that relationship in the documentation for 2.11.

I’m naively trying to write a RuleSource plugin that appends a new Ivy repository to the Repositories collection. I’ve tried various configurations such as:  
`ModelMap<ArtifactRepository>`, `ArtifactRepositoryCollection` etc. For each attempt I get a similar error message:

```
subject:
        - <no path> ArtifactRepository (parameter 1) [*]

```

Is `Task` the only interface that has been migrated to a Managed type at the moment?

Thanks for any advice!
