使用EF4.1 RC数据注释时是否有注释导致级联删除？

public class Category
{
    public int Id { get; set; }
    [Required]
    public string Name { get; set; }
    public ICollection<Product> Products { get; set; }
}

public class Product
{
    public int Id { get; set; }
    public string Name { get; set; }
    public Category Category { get; set; }
}

使用此模型生成的约束是:

ALTER TABLE [Product] ADD CONSTRAINT [Product_Category] 
FOREIGN KEY ([Category_Id]) REFERENCES [Categorys]([Id]) 
ON DELETE NO ACTION ON UPDATE NO ACTION;

如果不是如何实现？
