Doc formatting : Field API structures missing on a.d.o

field.crud.inc contains an extensive description of the $field and $instance data structures :
http://api.drupal.org/api/drupal/modules--field--field.crud.inc/7/source

That description is supposed to appear on the "Field API data structures" page at http://api.drupal.org/api/drupal/modules--field--field.crud.inc/group/fi..., but is currently being cut off, probably because of ill-formed PHPdoc.

Hints welcome on the proper PHPdoc syntax to use ?
