public @interface ConditionalUrlParam
```
On the Update, Create and Delete operation methods, this annotation can be used to mark a String parameter which will be populated with the conditional "search" URL for the operation, if an incoming client invocation is a conditional operation. For non-conditional invocations, the value will be set to null so it is important to handle null.
Parameters annotated with this annotation must be of type String
