Hi,

I feel that removing the sentence will lead to interoperability issues 
in the future - it would be better to simply clarify the issue as Jim 
suggests. How about something along the lines of the following:

"If a property in the current resource under scan has not been set to a value (either because the property itself is undefined or the property is empty for the current resource), then the value of that property is undefined for the resource under scan."

Perhaps another sentence to explain how undefined values are sorted?
