Example

var doc = new openXml.OpenXmlPackage(blankDocument_base64);
var mainPart = doc.mainDocumentPart();
var xDoc = mainPart.getXDocument();
var firstPara = xDoc.descendants(W.p).firstOrDefault();
var newFirstPara = new XElement(W.p,
    firstPara.attributes(),
    new XElement(W.commentRangeStart,
        new XAttribute(W.id, "1")),
    new XElement(W.r,
        new XElement(W.t, "This is a paragraph that contains a comment.")),
    new XElement(W.r,
        new XElement(W.commentReference,
            new XAttribute(W.id, "1"))),
    new XElement(W.commentRangeEnd,
        new XAttribute(W.id, "1")));
firstPara.replaceWith(newFirstPara);
var comments = new XElement(W.comments,
    new XAttribute(XNamespace.xmlns + "w", wNs.namespaceName),
    new XElement(W.comment,
        new XAttribute(W.id, "1"),
        new XElement(W.p,
            new XElement(W.r,
                new XElement(W.t, "A comment")))));
var newCommentPart = doc.addPart("/comments.xml",
    openXml.contentTypes.wordprocessingComments,
    "xml", comments);
mainPart.addRelationship("rId9999",
    openXml.relationshipTypes.wordprocessingComments,
    "../comments.xml", "Internal");
return {
    returnedDocument: doc.saveToBase64(),
    defaultDocumentName: "DocumentWithComment.docx",
    output: ["This example added a comment to the document.",
