Dear all,

The scope note for E8 Acquisition starts by saying …

This class comprises transfers of legal ownership from one or more instances of E39 Actor *to one or more other* instances of E39 Actor.

[emphasis added]

Yet example 5 is the loss of title due to the object’s destruction. In this instance surely the ownership is transferred to no one, and thus the first sentence should be to *zero or more* other instances of E39 Actor?

Indeed! :-)

I think we have described this as exception, not to make it too complicated. It could be from zero to many, and to zero to many, but not zero to zero...

I prefer not to write this in one phrase, but our FOL friends may spell this out!
