Section 2.2 says:
In cases where there is more than one field of only zeros, there is a choice of how many fields can be shortened. 2001:db8:0:0:0::1 2001:db8:0:0::1 2001:db8:0::1 2001:db8::1
It should say:
In cases where there is more than one field of only zeros,there is a choice of how many fields can be shortened, but must be shortened to its maximum capability. 2001:db8:0:0:0::1 is NOT acceptable 2001:db8:0:0::1 is NOT acceptable 2001:db8:0::1 is NOT acceptable 2001:db8::1 is CORRECT
Notes:
Applying section 4.2.1
