Hi Mickael! Each content type consists of the following pieces: - Node (model) [1] - Component (visual representation) [2] - Converter (optional, used to map from and to XML/HTML) [3] The verbose output for heading1 you see is just the DOM projection of the data, which is custom and can be specified in the Component implementation [2]. Often you need to add extra markup and interactive elements, so that's why for Substance content (data) is not rendered 1:1 but through a custom renderer component. Please have a look at the examples [4], which includes minimal but functional implementations using most of the available concepts.
