As I stated above, the licensure facts as I stated them are verifiable in Attachment Therapy on Trial (ISBN 027597675), pp. 44-45.  So the claim may have been made in good faith, but so is the correction.  Since my secondary source (which is peer-reviewed, professionally edited, and from a reputable publisher) takes its facts from the trial transcript, and it specifically relates this matter, it trumps the tertiary sources cited above.  To the extent that they differ from the book on this issue, they are wrong.
