Subject: [PATCH] Bug 7345: Enable exporting records sans private fields
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add an option for marcstd to the opac-export.pl and catalogue/export.pl
scripts. This new format removes all 9XX, X9X, XX9 fields and subfield $9
(with the exception of 490 in flavours of MARC other than UNIMARC). The work is
done in C4::Record::marc2marc.

Testing plan:
1. Export a record in "MARC (Unicode/UTF-8)" format as a control
2. In the OPAC, run the following jQuery to add the marcstd option to the UI:
> $("#export #format").append("<option value='marcstd'>MARC (no 9xx)</option>");
3. Export the same record in "MARC (no 9xx)" format
4. Compare the two, noticing that any subfield $9 or fields including 9 (other
   than 490 in flavours of MARC other than UNIMARC) have been removed

Test done under UNIMARC flavour. All seems to work well.

Test done under MARC21 flavour, works fine.
