if I understand it, this would require us not doing anything - i.e. 
this is the current situation (assuming we fix the annotation issue 
per today's telecon)

  it seems to me that this is completely and RDF issue, and only 
impacts OWL because OWL documents are RDF documents (making us 
uniquely qualified to comment on them) - if that is true, I would 
support the third option, with a recourse of going to option 1 or 2 
if RDF Core doesn't comply  - this latter might or might not be a 
threat to our LC status depending on how liberally one interprets 
"editorial change" and if we hold off creating a test case until we 
hear from RDF Core - seems to me endorsing option 1 requires the 
least work...
