COMMONS13 — Poor definition of ctxtdsg:isUsedBy

The phrase "is employed in the process of accomplishing something for" is poor English: specifically the final word "for".
I'm not even sure why it's even in ContextualDesignators since it's not referenced anywhere.

It's certainly not formally defined enough to be used to represent the notion of a restricted legal currency for a country.as in
<owl:Class rdf:about="&fibo-fnd-acc-cur;Currency">
...
<rdfs:subClassOf>
<owl:Restriction>
<owl:onProperty rdf:resource="&cmns-cxtdsg;isUsedBy"/>
<owl:someValuesFrom rdf:resource="&cmns-loc;GeopoliticalEntity"/>
</owl:Restriction>
</rdfs:subClassOf>
And this is nothing to do with the notion of context.

There is also inconsistent usage - the above is use by a geopolitical entity; there is also fibo-fnd-acc-cur:CalculatedPrice uses PricingModel which is not an entity and has quite different semantics.
