(back from vacations)

For 2 reasons :
- because $3 is unimarc-specific & we want to be marc-flavour independant
- if we want to use $3 only, then we have to use either an internally 
number or an external one, depending on wether we use a local authority 
entry or a public one (like Rameau thesaurus, for example, where $3 is 
FRBN045646897987...) that's more complex to developp ( & the less i do 
the better i feel, shame on me ;-) )
