Not really. The text you quoted does not state whether "::" MUST always
be used if it is possible to do so. It only states that when used, it
must be used to the maximum capability.
I disagree. The rule plainly states that "::" must be used to its
maximum capability. I view that as saying you must use it if it is at
all possible AND use it where it creates the highest level of
compression. I don't see any wiggle room in the rule to allow someone
to not use "::" when it can be applied.
Since we are reading the same text and coming up with different
conclusions, I would argue that the text needs tightening. In fact this
issue came up because of a post to the IPv6 mailing list by Brett Tate
in April asking the exact same question.
http://www.ietf.org/mail-archive/web/ipv6/current/msg11684.html
The exact question he asked was
"Concerning "::" usage, is the requirement that
1) "::" MUST be used when valid, or
2) only that if used, it MUST be used to its maximum capability?"
Cheers
Suresh
