Hi Mike,

thanks again for your comments.  Sorry I could not respond earlier - I 
am currently in the (time consuming) process of looking for a new job :)

I will send the current draft to Jeff soon - it should be listed.

I have cleaned this up, following your suggestion in the follow up email.

I wouldn't read the current statement as a negative statement.  I 
mention that all parts "can be linked to", which sounds like an 
additional feature to me.  However, I don't really see how privacy can 
be added in OWL.  Neither is better or worse, but both approaches 
fulfill their design goals.

This is a great idea and I have done some partitioning for the next draft.
