xsi:nil - is '1' allowed

3.2.7[1] of part 1 states that the xsi:nil attribute is of type boolean.

2.6.2[2] states;

 An element may be ·valid· without content if it has the attribute xsi:nil
with the value true.

Some people interpret the above statement to mean that '1' is not allowed as
a value of xsi:nil. Should this be on the errata list?
