Good questions. Yes, we use the word attach broadly
as you suggest. And yes, it would be fair to say that
most sites will not be able to use the non-identifiable attribute.
Basically, to use this attribute, a site is going to have
to go to extra legnths to scrub their web logs to make
sure that the pseuodononymous info they have on people
cannot be linked back to a real person. At minimum this
would require truncating IP addresses in the web logs.
