Mapping is the spirit of any ORM tool.

And as I knew about NHibernate that there is two techniques to do that:

(1) XML mapping
(2) .NET Attributes

I want to know what is the preferred one? and why?

As my opinion I think that Using XML mapping is better for complex applications as i can isolate mapping from my entities and that offer more Interdependency.

what is your opinion?

I prefer XML. If you use attributes, you are basically decorating your business classes. In my opinion this is mixing your persistence layer with your domain. XML lets you separate the mapping from the domain.
