Re: OWL 2 SS&FSS spec. editorial errors, comments

Dear Daniel,

Thank you for your comment
on the OWL 2 Web Ontology Language last call drafts.

Thank you for your careful proof reading. Most of the problems you  
identified had either already been fixed or have now been fixed --  
please see the relevant diff for details [1].

Regarding "side-effect", the hyphenated form is in the OED [2], so we  
didn't change it.

Regarding xsd:hexBinary and xsd:base64Binary, Section 2.2.3 of the  
XSD 1.1 specification states that "For purposes of this  
specification, the value spaces of primitive datatypes are disjoint,  
even in cases where the abstractions they represent might be thought  
of as having values in common." Thus the value spaces of  
xsd:hexBinary and xsd:base64Binary are disjoint, as both are  
primitive datatypes.

Regarding an annotation property providing an annotation for an IRI,  
this is correct. This is because punning can be used to associate the  
same IRI with more than one entity.

Regarding individual equality axioms, we do intend equality and not  
identity: stating that two individuals are equal means that they  
denote the same element, not that the individuals themselves  
identical (which they clearly are not).
