Hi Christine,

I agree with your remark on the pointers. In fact, I was just drafting  
a message to that effect.

I feel that the current way of linking from QRG to other documents is  
suboptimal, and I would prefer either a separate column that contains  
all (max) three links to Primer, Syntax and NF&R, or three separate  
columns.

Furthermore, the first column of the table is now called "Language  
Construct", whereas these are just descriptions of features of OWL 2  
(and OWL 1). I don't see the benefit of having a column 'equivalent  
classes' that shows the Functional Style syntax 'EquivalentClasses'  
axiom, and the RDF syntax 'owl:equivalentClass', i.e. the first column  
seems to be superfluous in many cases. Perhaps it should be beefed-up  
a bit, e.g. 'subclasses' could be 'Subclasses, class subsumption',  
'equivalent classes' could be 'Equivalent classes, class equivalence'.  
This would improve findability of the features listed.

See some of my fiddling here [1].
