I realise that I was not quite rigorous in what I said about 
transitivity in my message earlier today. To  clarify, as I understand 
them to be used in the thesaurus community and in ISO standards:

The generic relationship BTG is transitive

The partitive relationship BTP is transitive

The generalised  relationship BT can not be assumed to be transitive, 
because different occurrences of it may represent a mixture of the above 

Transitivity does not arise in the instance relationship BTI because you 
can't have an instance of an instance.
