comment.SetText("My comment.");

// Place the comment at a node in the document's body.
// This comment will show up at the location of its paragraph,
// outside the right-side margin of the page, and with a dotted line connecting it to its paragraph.
builder.CurrentParagraph.AppendChild(comment);

// Add a reply, which will show up under its parent comment.
