Description

It would be nice if sling provide support for feature flags (also called toggles) pattern [1].

I am thinking the implementation could provide the following.
1) Integrate an existing framework such as togglz [2] or implement something similar with UI/Configuration to toggle features.
2) Create a jcr property (sling:Feature) which can be added to resource type nodes. Then some conditional logic in <sling:include>, and get and post servlets determines if the resource should be rendered if its resource type contains such property.
