Inconsistent use of the word 'plurality' in the annotations of 'object aggregate'

[avsculley]

In the skos:definition plurality seems to mean greater than or equal to 1 whereas in the second skos:scopeNote it seems to mean greater than 1.

I am, of course, happy to submit a PR fixing this issue, if permitted. I think the fix is just to change the greater than or equal to symbol in the def to a greater than symbol.
