If I have missed any other postings of review comments re. -63 rev.4, apologies. 
I’ve gone for reviewing -63A before anything else, normative clauses only, and its slow going.  Maybe we need to divide and conquer – some on A, some on B, some on C?  I suspect the base doc is worthy of attention from everyone since it, theoretically at least, affects A, B and C ?

Anyway, here are my scattered thoughts thus far.
