Please prove that I am invalid ODF 1.0 (ISO 26300:2006). I do not think that I am. In fact I think that your statement that there are no valid ISO ODF documents in the world, and that there cannot be, is a brash, irresponsible and indefensible piece of bombast that you should retract.</text:p> <text:p>(Please note that this document contains no ID, IDREF or IDREFS attributes.
