DSLQuery with fragments

Hi. Is it possible to create query with dsl if I need to pass a fragment or inline fragment within query?
No examples for that, and search didn't help either.
For example I want to create something like this:
```gql
query getNode {
  node(id: "1234") {
    id
    ... on Model {
      id
      name        
    }
  }
}
```
