--------------------------------------

Ah, yes, Andy.  My bad.  However, the two issues are related.  I'll add it over there.

> It would be usefull that the JDO Query Langage could do some UPDATE and DELETE on Persistent
Object like this :
> UPDATE [<candidate-class>] SET item1=<newValue>, item2=<newValue> [WHERE
<filter>]
> The new_value specified for an update operation must be compatible in type with the state-field
to
> which it is assigned.
> Bulk Update must modify the value of the version column and refresh Level1 and Level2
cache.
> DELETE FROM [<candidate-class>] [WHERE <filter>]
> By default Bulk Delete is appy on the specified class and its subclasses and doesn't
do cascade delete.
> A keyword like CASCADE must be set if we want to does a cascade delete : 
> DELETE CASCADE FROM [<candidate-class>] [WHERE <filter>]
