As RFC4291, 2.2.1 is not really a section, I assume you mean:
8<----------------------------------------------------
2.2.  Text Representation of Addresses

   There are three conventional forms for representing IPv6 addresses as
   text strings:

   1. The preferred form is x:x:x:x:x:x:x:x, where the 'x's are one to
      four hexadecimal digits of the eight 16-bit pieces of the address.
      Examples:

         ABCD:EF01:2345:6789:ABCD:EF01:2345:6789

         2001:DB8:0:0:8:800:200C:417A

      Note that it is not necessary to write the leading zeros in an
      individual field, but there must be at least one numeral in every
      field (except for the case described in 2.).
----------------------------------------------------->8

And thus when I submit "whois -h whois.ripe.net 2001:0db8:1234/64"
it would return an inet6num with (the /48 exists, the /64 doesn't) :

2001:db8:1234::/48

Is that what you meant?

From my point of view, what I do is *always* rewrite the addresses
to the compressd form and in lowercase (caps are to screamish ;)
