I guess I would like to have some official guidance on that. Ralph, 
Guus, David, any opinions? Search for the two places where "Ontopia 
Knowledge Suite" is mentioned in the document [1].

Regardless of the guidance on that, what probably raised a red flag for 
me was the way it was mentioned. Something like "Garshol sketches some 
solutions for the tricky cases along the lines of X, which has since 
been implemented in the Ontopia Knowledge Suite". However, unlike for 
all the other approaches, there are no details of how these tricky 
questions are addressed. Given that this is the whole point of the 
note, this lack of detail is a concern. Basically, if it is a simple 
omission (which I am almost sure it is), then this is an easy fix. If 
you cannot provide details for proprietary reasons, then I think 
putting a plug for the tool could be problematic. Again, some help from 
people more familiar with W3C processes would be appreciated.

I agree.

Well, I think having "semantic" and "XML" in the same sentence is just 
too contentious and I am pretty sure others in this group would agree 
(if not argue more forcefully). XML is used a syntax for many SW 
languages, but calling it a "semantic web metamodel" is probably a 
stretch, since it doesn't have any explicit semantics.

Good - so, it's not an issue.

I feel so silly now :) Indeed, I read it on paper (it's 35 pages, hard 
to read on screen), and it hasn't occurred to me that these would be 
links :) so I just used google. Indeed, putting URLs in the reference 
would be helpful, and I think is a reasonably common practice,
