Section 4.2.1 says:
The line > The use of the symbol "::" MUST be used to its maximum capability. … contradicts the next section, which states that single-0 fields are not reduced. i.e., this: > 2001:db8:0:1:1:1:1:1 … is longer than: > 2001:db8::1:1:1:1:1 Thus, the standard does not, in all cases, require that "::" be used to its maximum capability.
It should say:
The first line of 4.2.1 should be amended to be consistent with section 4.2.2 > The use of the symbol "::" MUST be used to its maximum capability to reduce consecutive 16-bit 0 fields.
