The International Nucleotide Sequence Database format is used to represent annotated
nucleotide sequences in xml format. More information on this format is available
at www.insdc.org.
Example:
<?xml version="1.0"?>
<!DOCTYPE INSDSeq PUBLIC "-//NCBI//INSD INSDSeq/EN" "http://www.ncbi.nlm.nih.gov/dtd/INSD_INSDSeq.dtd">
<INSDSeq>
(each sequence is surronded by these 2 elements)
</INSDSeq>
