REST web service is it possible to PUT a List

Hello,

i'm doing a new REST web service

I managed to PUT an Employee using xml format but I wanted to know if it's possible to put employee list always with XML format ?

in the interface we can have something like that:

[OperationContract]
[WebInvoke(Method = "PUT", RequestFormat = WebMessageFormat.Xml, BodyStyle = WebMessageBodyStyle.Bare, UriTemplate = APStatusUriTemplate.UpdateEmployeeList)]
int UpdateEmployeeList(List<Employee> UpdateEmployeeList);

and in the svc.cs 

public int UpdateEmployeeList(List<Employee> updatedEmployeeList)
{
    return Business.BusinessAccessLayer.UpdatedEmployeeList(updatedEmployeeList);
}

I wanted to know What I should put in the Employee Model class to do that 
the xml provided will have Employees root node and several Employee sub nodes

thanks in advance
