Note that in the coming 2.0 version of koha (full marc compliant 
version), it's the db structure we use to store marc records (except 
that we have no marc_data table).

to support any marc flavor, we also have 2 parameters table that 
explains "what" a tag/subfield means. Those parameters tables already 
exists in marc21 (in english) and unimarc (in french)

PS : the 2.0 version should be here in 2003Q1 (february i hope)
