      <!-- note on the offset value here: this can only be as big as
           MimeTypes#getMinLength(). If you set the offset value to larger
           than that size, the magic will only be compared to up to
           MimeTypes#getMinLength() bytes. It should also only start after
           the higher priority "start of file" one above
