Suggestion for change to DAML+OIL walkthru

In the DAML+OIL walkthru[1], I think the Adult and Senior classes should
have 

<daml:toClass
rdf:resource="http://www.daml.org/2001/03/daml+oil-ex-dt#over17"/>

instead of 

<daml:hasClass
rdf:resource="http://www.daml.org/2001/03/daml+oil-ex-dt#over17"/>

(and same with "over59" for Senior).

It doesn't technically matter in this case, because age is defined as a
UniqueProperty, but "hasClass" makes it sound like they can have several
ages and one of them should be "over17/over59", and just sounds less
intuitive.
