Serializing an XmlArray with attributes

Hi

I'm currently having trouble serializing an object to Xml, in the format I
need.
Below is the object definition.

-------------------------------
[Serializable]
public class Folders
{
protected List<PathString_include;
protected List<PathString_exclude;

public Folders()
{
_include = new List<PathString>();
_exclude = new List<PathString>();
}

[XmlArrayItem("Include")]
public List<PathStringInclude
{
get { return _include; }
set { _include = value; }
}

[XmlArrayItem(ElementName="Exclude",Type=typeof(Pat hString))]
public List<PathStringExcludes
{
get { return _exclude; }
set { _exclude = value; }
}
}

[Serializable]
public class PathString
{
protected string _path;

[XmlAttribute]
public string Path
{
get { return _path; }
set { _path = value; }
}

public PathString()
{
}

public PathString(string path)
{
_path = path;
}
}
--------------------------

From these objects, I want my Xml output to look like :

<Folders>
<Include Path="Path1"/>
<Include Path="Path2"/>
<Exclude Path="LessTrodden"/>
</Folders>

However, I am having trouble getting the correct output.
The code above produces the following :

<Folders>
<Include>
<Include Path="Path1"/>
<Include Path="Path2"/>
</Include>
<Excludes>
<Exclude Path="LessTrodden"/>
</Excludes>
</Folders>

I want to use List (or IList) as I want to bind my object to a DevExpress
TreeList
Does anyone have an idea of how I can get my required output ?

Cheers
