Description

With the current feature set, a resource provider mounted at a sub path is overlaying a potential parent resource provider.
For uses cases like for example adding additional information to some of the resources, the overlay mechanism is very complicated to implement. It requires to pass through all resources, but also to deal with obersation, querying and modifications.
A new mode named PASSTHROUGH could be implemented to make this easier and let the resource resolver fall back to the overlayed resource provider taking care of modifications, observation etc.
