Generic of type T where T has a specific attribute

Question

Is it possible to create a generic method of type T where T has a specific attribute?

E.g.:

public static XmlDocument SerializeObjectToXml<T>(T obj)
{
    //...
}

and I want to serialize only a classes with a Serializable and/or DataContract attribute:

[Serializable]
[DataContract(Name = "viewModel", Namespace = "ns")]
internal class ViewModel
{
    //...
}

Perhaps you can do it indirectly, by creating a base-class which has the Serializable attribute, and add a constraint to your generic class, so that the type-parameter should inherit from that base-class:

[Serializable]
public class MyBase {}

public static XmlDocument SerializeToXml<T>( T obj ) where T : MyBase {}
