it is safe to delete anything from embl except the ID line. If you have only
SwissProt and EMBL then the link information (as is the default anyway) will
be supplied by SwissProt...but this link utilizes the EMBL accession numbers -
don't delete them! 

The SRS indexing system does not complain about
missing data-fields but 'srscheck' will try to rebuilt missing indices - so you
should outcomment all fields in embl.sdl except the ID field


..almost forgot ...better use the Perl script for removing data-fields!
