Dan:

I don't see how you can say this.  In my view, both of Jim's special
requests for feedback go far beyond what should be included in a request
for general feedback on a set of documents.


By the way, I would feel just as strongly if Jim had said something like:

	We would particularly like feedback on whether basing OWL on RDF is
	a good or bad idea.

One reason that such requests are a bad idea is that they bias the
feedback.  For example, how can anyone who believes that stopping at OWL
Lite is a good idea now use any feedback to bolster their position?
