I have a XML tag that I am submitting I need to only show half of the opening tag for the closing

I am a rookie just started XML about a week ago, so I apologize if this is an easy question but I have searched on the Stack and cant find my answer. This is what I currently send

<BURGER_REQUEST_WHOPPERVersionID_2.4 _ActionType="No Pickle" _CommentText="">
</BURGER_REQUEST_WHOPPERVersionID_2.4>

This is what the company said I need to be sending

<BURGER_REQUEST _WHOPPERVersionID_2.4 _ActionType="No Pickle" _CommentText="">
</BURGER_REQUEST>

This is is my code using C#.

  XElement burgerRequestNode = new XElement("BURGERREQUESTVersionID_2.4",

            new XAttribute("_ActionType", "Original"),
            new XAttribute("_CommentText", string.Empty));
        XElement productNode = new XElement("_PRODUCT",
            new XAttribute("_CategoryDescription", burger.ProductDescription));
        XElement typeNode = new XElement("_TYPE",
            new XAttribute("_Identifier", burger.ProductIdentifier));
        productNode.Add(typeNode);
        requestNode.Add(productNode);
