I believed that the point was that,
a domain ontology would, for most domains, especially scientific ones, need to include references to special individuals,
Yes, but what is important is to unambiguously identify individuals from classes. For that purpose the identity criteria introduced in OntoClean is of utmost importance. For example:
like zero, -> criteria of identity: its symbol
like the chemical elements, -> criteria of identity: its chemical symbol in the Mendeleev table
as individuals, like the earth, -> criteria of identity: its name
This approach works well for people called 'Smith'.
