N3936 20.6.1 [bitset.cons]/6 says: "An element of the constructed string has value zero if the corresponding character in str, beginning at position pos, is 0 zero. Otherwise, the element has the value 1."

First, "0 zero" appears to be the result of an editing mistake. It should be "zero" (in monospace, because it's a parameter name).

Second, "value zero" and "value 1" are inconsistent about words versus numbers. It should be "value one" (ordinary, not monospace), for consistency with other wording like /35's "Bit value zero" and "bit value one".

Third, this says "constructed string", but a bitset isn't a string. It should probably say "constructed object".
