ISO and other standards bodies did not learn from the OOXML debate. Reform of ISO is pending to allow more fast tracked standards from ECMA.
I doubt reform is possible.
Others might have a different opinion:
Thomas Vinje, the lawyer of ECIS, raised the issue at the recent OpenForumEurope (OFE) Summit (the one where Neelie Kroes praised "open" standards) of compatibility of the OOXML ISO specification with the procurement directive, which forbids product naming and platform dependencies. This is indeed an interesting question that needs to be investigated. Does OOXML still has platform dependencies? If yes, what would happen if the specification is required in a public tender?
