Is there a way to create a class that derives from XElement, but also control the types of objects that can be added to it?

For example, say I have this…

public class HtmlHead : XElement {}

But I can’t override the Add() method because it’s down at the XContainer level. And even if I was to create a class that derives from XContainer I still don’t have access to override the Add() methods.

Why would I want to do this, you ask?

I want to make sure that if my program compiles that it also parses the HTML correctly. Like, you can only add certain elements to an HTML <head> tag, so I want to make sure only supported tags can be added.

Surely, you won’t be adding an <anchor> tag to the <head> tag—ya’ feel me?

    You can control the passed name via the constructor.

    public class HtmlHead : XElement
{
    public HtmlHead(object content) : base("head")
    {
        this.Add(content);
    }

    public HtmlHead(params object[] content) : base("head", content) { }
}

    When an item is added, change notification is performed or you can create a custom method for adding which everyone should use.
