How to shim XmlAttribute using Microsoft Fakes in VS 2013

I have the below code I am testing.

    public Loader(XmlAttributeCollection attributes)
    {

        if (attributes == (XmlAttributeCollection)null)
            throw new ArgumentNullException("attributes");
        foreach (XmlAttribute attribute in attributes)
        {
            if (attribute.Name.Equals("name", StringComparison.OrdinalIgnoreCase))
            {
                name = attribute.Value;
            }
            else if (attribute.Name.Equals("type", StringComparison.OrdinalIgnoreCase))
            {
                loaderType = attribute.Value;
            }
            else
            {
                loaderAttributes.Add(attribute.Name, attribute.Value);
            }
        }
    }

Is that possible to shim the attribute/attributecollection so that I can return whichever the attribute object I want to return ?

For example I want to return two xmlattribute objects one with attribute name of "name" and another one as "type" and also their respective values .
