A generic object that represents a length of text and its associated properties in a rich text form field or annotation. A rich text value consists of an array of span objects representing the text and formatting.

Note:Span objects are a copy of the rich text value of the field or annotation. To modify and reset the rich text value to update the field, use the Field object richValue property, or the Annotation object property richContents, and the event object properties richValue, richChange, and richChangeEx.
