I see, so  "H]C]C" would allow one to have one home, two cell and no
international #s.



Is there a db level mechanism that ensures changes to a thing will be
reflected or synchronized with other representations of the same thing
in the db even if they are one of mulitiple values in various fields?



Also if some phone#  have suparts (ie extentions, hours of operation,
alternate number, etc), how would the sub parts be stored without
redundancy?
