[oslc-core] Ambiguity in Resource Shape definition + consequent questions

[John Arwe]

+1 -- Arthur's simplification is fine -in the context of- the description 
of oslc:describes on a ResourceShape.  It says nothing limiting, so 
oslc:instanceShape is simply orthogonal.
Q2-Q6 are updates to the text in that section (larger context), and they 
*do* need to avoid precluding oslc:instanceShape, hence the "...or 
instances..." phrase in Q2/Q4 proposals.

Best Regards, John

But I think there's one more case covered by John's description:

A shape S applies to a resource R if there is a triple R 
oslc:instanceShape S

This covers the case that R doesn't declare a type, but still says that S 
is it's shape (independent of what shapes S describes)
