StructuredDocumentTag tag = new StructuredDocumentTag(doc, SdtType.PlainText, MarkupLevel.Inline);

// Set the "LockContents" property to "true" to prohibit the user from editing this text box's contents.
tag.LockContents = true;
builder.Write("The contents of this structured document tag cannot be edited: ");
builder.InsertNode(tag);

tag = new StructuredDocumentTag(doc, SdtType.PlainText, MarkupLevel.Inline);

// Set the "LockContentControl" property to "true" to prohibit the user from
// deleting this structured document tag manually in Microsoft Word.
tag.LockContentControl = true;

builder.InsertParagraph();
builder.Write("This structured document tag cannot be deleted but its contents can be edited: ");
builder.InsertNode(tag);
