Remarks

To create a comment anchored to a region of text, you need to create a Comment and then create CommentRangeStart and CommentRangeEnd and set their identifiers to the same Id value.

CommentRangeEnd is an inline-level node and can only be a child of Paragraph.

Examples

Shows how print the contents of all comments and their comment ranges using a document visitor.
