    We have adopted that in our current spatial ontologies, using the term 
    "locus" because "location" had connotations to our customer.  The 
    notion of "locus" has child subclasses of Point Locus, Linear Locus, 
    Area Locus, and Volume Locus.
    We find that the blurring of distinction between point and area is 
    sometimes useful when discussing things like cities.  For some purposes 
    they are usefully modeled as points, in other cases, it is more 
    appropriate to reference the associated territory within the city
