In Section 6.2.4, op:numeric-divide, we read "Division by negative zero
returns -INF ..." and we also read "Zero divided by zero ... returns NaN."
There is a potential for confusion about which rule applies in certain cases.
Proposal: replace the last sentence in the Note in this section as
follows: "Positive or negative zero divided by positive or negative zero
returns NaN. Also, INF or -INF divided by INF or -INF returns NaN."
(This clarification is consistent with IEEE 754, which is normative. The Note
at the end of Section 6.2.4 is simply provided for the convenience of the
reader.)

Closing bug because commenter has not objected to the resolution posted and more than two weeks have passed.
