The workshop is led by a moderator.
The group might consider whether the pattern has the "quality without a name" or how the pattern makes the programmer's life easier.
Others in the group who also "know" the pattern should not try to clarify or speak for the author during the discussion. The pattern should "stand on its own."
The moderator should constrain the discussion to the pattern at hand, usually with a comment, "point noted" and then proceed with the workshop. Issues can be directed to a parking lot for consideration after all patterns in the workshop have been discussed.
The expectation is that the author is an expert in the area and will act appropriately to suggestions. There is no need to "check" on whether the suggestions are taken to heart. However, the author can request a second workshop as a helpful next step.
