+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.

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)
