Because of the form the wine ontology has taken, in order to make 
the Guide presentation sensible, I had to move hasValue back before
most of the Full OWL constructs.  So this would mean nothing
more than deleting the OWL/Full tag from hasValue.  And the
presentation would be more easily adapted to a presentation 
that covered all of OWL Lite before introducing OWL Full elements.

Hmm... it raises the issue clearly enough; do you really
mean for this to be a proposal to close it as well?

I don't feel strongly one way or the other; I don't have
much stake in what's in owl Lite and what's not.

But in order for me to agree to close this issue, I'd
like to know more about the impact on other documents...

Could you elaborate that into a test case, or a sketch of one?
Maybe a few paragraphs for the guide? Hmm... I suppose
hasValue is already in the guide; it's just a matter
of whether it's designated as part of owl Lite.

I suppose the impact on the feature synopsis is just one
line, or maybe a paragraph or two.

How about semantics? Is OWL lite semantics just the
fast semantics applied to the lite syntax? I'm
still a little hazy there.

Any change to the reference document involved?
