Hibernate version: 3.0

I'm looking for a way to override selected named queries depending on the database dialect used. I see that this is supported via dialect-scope for database objects. Is there an easy way to either include mapping resources depending on the dialect if it is not possible to scope them by dialect within the resource files? (We are using the Spring -> Hibernate integration but I'm not aware of respective support in Spring either.)

Is there a plan to extend the support for dialect scoping in future releases?

Thanks,
Thomas
