if it's not too late, could you give some thought to the following three 
minor comments:

> Class Definition
>     informal term for talking about an owl:Class element and its descendant elements

What's a "descendant element"?

> Class name
>     informal term for refering to an owl:Class tag.

'Tag'? Isn't the class name the term contained by the owl:Class element?


> Individual
>     an instance of an OWL class, i.e., a resource that belongs to the class extension of an OWL class
> Instance
>     a member of the class extension of an OWL class

It's not clear to me that there's a difference between an Instance and 
an Individual. I thought that the f2f editors' breakout session had 
decided not to include Instance as a noun. In
http://lists.w3.org/Archives/Public/www-webont-wg/2003Jan/0176.html
Chris indicates that
"instance: the relation between an individual and a class"
