Do you mean, you don't understand it because SUMO doesn't have an 
conflict? What I don't understand is how you are going to explain to 
a potential user of SUMO what a 'physical object' is. An ontology 
isn't just a set of axioms: it is also a perspective on how to extend 
and utilise those axioms to create other, new, axioms. Users need to 
be able to understand what the overall perspective is, so you need to 
be able to say what it is.

It doesn't allow the endurantists (3-d enthusiasts) to model things 
as THEY wish. See my earlier message for details.
