We'd better to define specific syntax for portability.

What is the desired delimiter?
KAME's '@' seems not good
other candidates
<scope_id>/<address> (used in MSR)
<address>-<scope_id>
are alphabetical characters better?
[S|s]<scope_id>:<scoped_address>
is "S12A:FEC0::123:4567:89AB:CDEF" easy to read?

What is the desired order of <address>, <delimiter>, and <id>?
is <scope_id> the most significant part?
if so, should it be placed before <address>?
