Can you put scenes and assets in the same assetbundle?

I am trying to build an asset bundle with a Scene and all the assets that scene needs in a single assetbundle but I am getting an error that says: Cannot mark assets and scenes in one AssetBundle. AssetBundle name is "game0bundle". But in the Unity tutorial on [AssetBundles And The Assetbundle Manager][1] says things like "AssetBundle is a collection of assets and/or scenes" which makes it sound like you can put both assets and scenes in the same assetbundle. So am I suppose to be able to put scenes and assets in the same bundle and I'm doing something wrong or is the tutorial just worded strangely?
