GUIDE:Few thoughts on the guide document

Hi Mike;

I went over portions of the guide document.  I have the following
comments/questions.
Apologies if those were  already covered on the mailing list.
In the section titled "design for use"
... "but the that describe a set of individuals, and individuals are the
members of those sets"

I found myself wondering if individuals are the same as instances of these
classes.  If so, why not use instances to explain individuals.


In section "simple property", hasWineDescriptor has a range another
objectproperty?

On page No. 14:

"It is now possible to expand the definition of Wine to include the notion
of regions..."

<owl:Class rdf:ID="Wine">
  <rdfs:subClassOf rdf:resource="#PotableLiquid"/>
  <rdfs:subClassOf>
    <owl:Restriction>
      <owl:onProperty rdf:resource="#madeFromGrape"/>
      <owl:minCardinality>1</owl:minCardinality>
    </owl:Restriction>
  </rdfs:subClassOf>
  <rdfs:subClassOf>
    <owl:Restriction>
      <owl:onProperty rdf:resource="#locatedIn"/>
      <owl:minCardinality>1</owl:minCardinality>
    </owl:Restriction>
  </rdfs:subClassOf>
  ...
</Class>


Earlier in the document, you had the following:
<owl:Class rdf:ID="Wine">
  <rdfs:subClassOf rdf:resource="#PotableLiquid"/>
  <rdfs:label xml:lang="en">wine</rdfs:label>
  <rdfs:label xml:lang="fr">vin</rdfs:label>
  ...
</owl:Class>
is that legal?  Know that label information is missing above.
