Description

In Sling scripts and servlets are equal [0]. However, currently a servlet cannot declare a resource super type property, in order to allow delegation / overlaying at runtime to another servlet, similar to how component scripts can do it through the sling:resourceSuperType optional property.

Adding support for another registration property - sling.servlet.resourceSuperType - that accepts a String as value would allow to introduce a backwards compatible overlaying and inheritance capability. This property should only be considered for the registration together with the sling.servlet.resourceTypes.
