so that the output of the rich text can be (almost) directly used to set the value of the field.
As an editor, I want to be able to fill the RichText with a rich text editor
Document the formats accepted by the RichText field types
Just one remark on the first sentence: "This FieldType validates and stores formatted text.", I would write "This FieldType validates and stores a structured text." instead. Other than that, it's good for me.
