Guus/I had an action item to review the text on Species of OWL in the guide 

In general, I think it is fine. Of course it omits details, but it gives the 
right flavour. Below one comment and some small editorial suggestions.

I think we should add a paragraph explaining the containment relation of 
these three languages, after the text describing OWL/Full. Something along 
the lines of:

"Each of these languages is an extension of its simpler predecessor:
Every legal OWL/Lite expression is a legal OWL/DL expression (but not vice 
versa) and similarly between OWL/DL and OWL/Full. Also, every valid OWL/Lite 
conclusion is a valid OWL/DL conclusion (but not vice versa), and again 
similarly between OWL/DL and OWL/Full."

- replace "complex" by "expressive" in two places
- move the sentence on "When we introduce constructs..." to after the 
description of OWL/Full.
- remove the bracketed remarks on class extension and intension. I'm not sure 
if this is used in precisely the right way here, and it will not help novice 
readers anyway.
- start the 2nd sentence in the OWL/Full paragraph with "For example, ", to 
indicate we're not being exhaustive here.

(oops, only now do I see our action item applies to the synopsis document;
 oh well, will do in a minute)
