hello!

i think i've found an error in the document at 
http://www.w3.org/TR/owl-features/
in the paragraph about  InverseFunctionalProperty

what is now written:

For example, hasUSSocialSecurityNumber (a unique identifier for United 
States residents) may be stated to be inverse functional (or 
unambiguous). The inverse of this property (which may be referred to as 
isTheSocialSecurityNumberFor) has at most one value for any individual 
in the class of social security numbers. Thus any one person's social 
security number is the only value for their

*isTheSocialSecurityNumberFor* property. From this a reasoner can 
deduce that no two different individual instances of Person have the 
identical US Social Security Number. Also, a reasoner can deduce that 
if two instances of Person have the same social security number, then 
those two instances refer to the same individual.


should i guess be:

For example, hasUSSocialSecurityNumber (a unique identifier for United 
States residents) may be stated to be inverse functional (or 
unambiguous). The inverse of this property (which may be referred to as 
isTheSocialSecurityNumberFor) has at most one value for any individual 
in the class of social security numbers. Thus any one person's social 
security number is the only value for their

*hasUSSocialSecurityNumber* property. From this a reasoner can deduce 
that no two different individual instances of Person have the identical 
US Social Security Number. Also, a reasoner can deduce that if two 
instances of Person have the same social security number, then those 
two instances refer to the same individual.


or is this just my flawed reasoner? :)
