modifying default attribute name

[Hugo de Paix de Coeur]

hi,

I'd like to share my addressbook between applications, so I'd like to 
use more generic attribute name of my own instead of
mozillaNickname, mozillaHomePostalAddress2, mozillaHomePostalCode, etc ....
how can i change this default behaviour without recompiling mozilla?

other question, how mozilla ldap manage more than 2 email address? 
(there are only mail and mozillaSecondEmail)

thx ..
