Overriding @GenericGenerator parameters

Hi,
I'm using the latest Hibernate Entity Manager + Hibernate Annotation packages and like to know if its possible to override paramters of a generator specified using the @GenericGenerator annotation.

An Example: Let's say for the following entity I want to have a different value for the max_lo parameter for the id generator depending on the environment the class is used in (e.g. making it configurable somehow)? Or Let's say I need to use completly different ID generators for different systems, how could I specify that without needing to change the annotation and recompile the class?

Code:

@Entity
public class MyEntity {
  @Id
  @GeneratedValue(generator = "oid")
  @GenericGenerator(
    name = "oid", 
    strategy = "org.hibernate.id.TableHiLoGenerator",
    parameters = {@Parameter(name = "max_lo", value = "1")}
  )
  private Integer oid;

  // ... other stuff here
}

Any ideas and comments are appreciated,
Johan

I'm working on the ability to override annotations by some XML descriptor.
