Description

In some cases it is not possible to know what statistics/attributes will be available on an object until runtime (for instance it may depend on the environment, the JVM in use or other factors). In this case we cannot define the statistics/attributes statically, but must instead inject them at run time.

Another use case is where new functionality may wish to store information as attributes against existing configured object types (e.g. an ACL system where permission information is stored at each object).
