The changes required to the various documents in order to implement
this change seem to be very minor. As far as I can tell they would be
limited to:


In Section 3.1 "OWL Lite RDF Schema Features", under "Classes", append
the sentence "There is also a built-in most specific class named
Nothing that is the class that has no instances and a subclass of all
OWL classes.".

In Section 4 "Incremental Language Description of OWL DL and OWL
FULL", under "complex classes", delete the sentence "OWL also includes
a special "bottom" class with the name Nothing that is the class that
has no instances.".


No change.


In Section 3.1 "Class descriptions", delete "NOTE: owl:Nothing is not
included in OWL Lite.".

In Section 8.3 "OWL Lite", delete "owl:Nothing" from list of things
forbidden in Lite.


In "Index of Vocabulary (Informative)", in the entry for
"owl:Nothing", add pointer to Section 2.1 in column labelled "Abstract
OWL Lite Syntax".

Editors of individual documents will no doubt want to double check to
see that I didn't miss anything.

Regards, Ian
