As far as "widely accepted" goes, if HTC doesn't accept fabricated documents, whether or not others choose to accept them as accurate means nothing. Waffle noted that the document is knock-off, which leads me to think they are looking for the real article, not just some pretty artwork that is purported to contain the correct data. It may well contain accurate data, but the fact that it is not a genuine document, although intended to look like one, leaves me suspicious as well.
