Cool!   So couldn't we use that as a general purpose type (2) smushing rule
?

If
   [nodeX, propertyY, whatever] and;
   [nodeY, propertyY, whatever] and;
   [nodeX, rdf:type, nodeZ] and;
   [nodeY, rdf:type, nodeZ] and;
   [propertyY, atMostOneEntityValue, "yes"];
then
   smush (nodeX, nodeY).

What is the actual name of this "atMostOneEntityValue" property and in what
schema(s) does it exist?

Please excuse my impromptu linguistic contrivances.
