ODT packaging, mimetype file

Hi,

ODF 1.2 spec says, that mimetype file SHALL be the first one in the ODT.

Why signed ODT documents do not have mimetype as the first file in  
the ZIP? ;-)

correct file:

00000000  50 4b 03 04 14 00 00 08  00 00 ed 49 23 3e 5e c6  |

wrong ODT file:

00000000  50 4b 03 04 14 00 00 08  00 00 31 3b 9d 3d 00 00  |

Do we create illegal ODT files?

Why do we open such files when they are not correct ODT files?
