C# - Add A Textnode Instead Of An Attribute In A .NET Configurationsection?

I currently have a .NET custom configurationsection that looks like this:

<customSection name="My section" />

What I want is to write it as a textnode (I'm not sure if this is the correct term?) like this:

<customSection>
<name>My Section</name>
</customSection>

My current customSection class looks like this:

public class CustomSection: ConfigurationSection {
[ConfigurationProperty("name")]
public String Name {
get {
return (String)this["name"];
}
}
}

What should I do to make it a textnode?
