+ There are a number of situations where the REST framework doesn't
+ actually know exactly what operation is going to be performed by
+ the implementing server code. For example, if your server implements

operation, the server might not know

+ is executed.

+ Because client code is actually determining which resources are + being modified, the server can not automatically apply security + rules against these modifications without being provided hints + from client code. +
++ In this type of situation, it is important to manually + notify the interceptor chain about the "sub-operation" being performed. + The following snippet shows how to notify interceptors about + a conditional create. +
