Section 5 says:
<end of section>
It should say:
Since -0 is a valid JSON Number but is serialized as 0, a JSON parser following this specification SHOULD generate an error condition (which in turn SHOULD stop processing) when it encounters -0, in order to thwart potential attacks on not yet parsed data.
Notes:
IEEE 754 includes as distinct values both positive and negative
zero. Section 7.1.12.1 of ECMA-262 says: If m is +0 or -0, return
the String "0". This may lend itself to erroneous input to
supporting functions.
