Thanks.

All seems good. Howvere, I'm not sure that the second section "The
primary motivation of changing from the OWL 1 abstract syntax (AS)
..."  is needed in that response. Unless there is extra info that I
don't know or missed, AS vs FS was not expliciley raised in the 2
quoted emails (1st or 2nd). I'd be inclined to remove it to remain
focused on their explicit content and not to extend our response to
that.

Nevertheless, since I believe it's highly relevant to document this
issue somewhere in our docs, we may add something similar in the
Syntax or/and in  NF&R. I have added it in the new drafted section 3
of NF&R [1].
