It is not possible to pass attribute style="value" to model by model utils and datacontroller

[oskarwrobel]

When we want to set attribute style with some custom value style="dark" to model element then view conversion cuts it off https://github.com/ckeditor/ckeditor5-engine/blob/fc7da8035cdc9533f66ad5de66711e25cd2b385e/src/view/element.js#L103-L107

Note that we will have this problem with any data processor other then HTML. On the editor.setData we parse the data to the "view" structure, and it assume that it is HTML-like (so parse styles and classes in the special way).

On the other hand in might be a correct behavior. Plugins which introduce converters assume that view is HTML-like, so data processors should not create invalid structure.

This made us name model attribute used by ImageStyle plugin as imageStyle instead of just style. We should try to fix this before 1.0.0.
