A quick question to all you IAFA hackers out there - are there any rules
for grouping variant fields in IAFA templates?  I assume that variant
fields with the same variant number after the ``-v'' are always supposed
to be a part of the same logical group.  In which case the numbering for
variant clusters should be different for unrelated clusters, right?  For
example in the DOCUMENT template type as Author-(USER*) and Admin-(USER*)
aren't really related but Language-v* and Format-v* are (probably), we'd have
something like: 

Author-Name-v1: Joe Bloggs
Author-Name-v2: Andy Capp
Admin-Name-v3: Fred Jones
Admin-Name-v4: Bertie Bassett
Language-v5: blah blah
Format-v5: related to blah blah
Language-v6: froop froop
Format-v6: depends on froop froop

Is this right?  The clusters must be marked as variants (ie: have the
-v<number> after the field name) otherwise one wouldn't know which email
address went with which name.  Are there any cases where variant clusters
_are_ related to other clusters or normal variant fields and so should
have the same numbering scheme?  If so, how does one workout from the
outline templates given in the I-Draft which ones these are?
