> Quite a few people have shown up recently on the mailing list and have expressed a wish to separate the rendering engine from the core itself, so that they wouldn't need so much baggage with the engine.
> Unfortunately, this is quite difficult, as the rendering engine does rely on quite a few bits from the WikiEngine instance, for example URL generation and checking whether a page/attachment exists or not, as well as settings.
> However, these things could be enumerated and isolated to a RenderingContext interface.  Then, anyone who would like to get their own engine would need to implement this interface.
> It may mean that WikiEngine and WikiContext might need to become interfaces as well.  However, that might not be such a bad thing, as it would give a more stable developer API.  Then we would have a three-layered architecture, where one layer (WikiEngine) takes care of static stuff, WikiContext contains per-request data, and RenderingContext provides the bits and pieces which are part of HTML generation.
> At any rate, this requires more thinking.  Probably not going to happen before 3.0 anyway.
