I'd advocate ISO-2709 only being an import/export format, and never
using it internally. It's just got too many limitations, as we're
seeing here.
On import, we check for valid leaders, and warn if not.
On export, we calculate the leader, and if it exceeds 99999, we warn.
We can develop several options for dealing with this, like truncating to
the appropriate length, skipping the record or just exporting with an
invalid leader.
Cheers,

It's not really about ISO-2709 format (afaik, MARCXML has the same
problem, leader must be 24 characters long), it's about MARC. And we are
using it internally through MARC::Record.
As we already have invalid MARC records (ie. longer than 99999 bytes),
and we want to keep the records as is, I think we should at least have a
well-formed (but invalid) leader with first five characters being
'99999', since sixth character will never be read to get the record
length anyway.
What do you think?
