How to use a composite id with mapping attributes?

Hello,

I'm trying to find out how to use a composite id with mapping attributes.

:?:
Is there an attribute dedicated for <composite-id>?
If not, is there a workaround (using a <component> or something like that?
:?:

I have 2 tables T_company and T_VAT described below.

T_company contains the columns : Id | company name
T_VAT contains the columns : companyId | VAT

I'd like to get the 2 fields of the second table in a composite id with mapping attributes.

Thanks a lot,
David

Here is an example: (from NHMA.Test)

Code:

[NHMA.CompositeId(0, ClassType=typeof(...))]
   [NHMA.KeyProperty(1, Name="Id")]
   [NHMA.KeyManyToOne(2, Name="Foo", ClassType=typeof(Foo))]
public int Id
{
   get { return _id; }
   set { _id = value; }
}
