Hello , I am not sure how to write this but I need to write a mapping xml file for a class this is my class definition :
public class Mail : IMail
{
public int ID
{
get;
set;
}

public IStatus MessageStatus
{
get;
set;
}
}


ISTATUS is an interface inherting from IDomain , and there is a class called status inherting class domain implemeting inteface Idomain

public class Domain : IDomain, IUserType
{

#region IDomain
#region ID
public int ID
{
get;
set;
}
#endregion

#region Name
public string Name
{
get;
set;
}
#endregion

#region ParentId
public int ParentId
{
get;
set;
}
#endregion
#endregion
}

so I'll be now having a mail class with the property IStatus , It'll be set to an enum or integer value , I made a little search and I found that there is an interface called iusertype i shall implement for class ( domain ) , is that right or what ?
