Denis' comment in this thread is accurate and I will reword the related checkpoints as follows: 5.2.2: When no alternative text representation has been specified, indicate what type of object is present. 5.2.3: When alternative text has been specified explicitly as empty (i.e., an empty string), render nothing. > 3.

Please propose wording for an appropriate checkpoint to the list. Thanks again, - Ian -- Ian Jacobs (jacobs@w3.org) Tel/Fax: (212) 684-1814 http://www.w3.org/People/Jacobs
