We output HTML4 to get some flexibility in the output, but I am not sure how useful the HTML4 doctype declaration is any more and perhaps we should switch to the simpler HTML5 "<!DOCTYPE html>" header. It looks like we are trying to conform to a standard that nobody cares about anymore. Does anybody object if I go and change texi2any to output this instead of the HTML4 Transitional doctype? As far as I remember the main difference is the use of the <tt> tag which has been removed from the standard, but I am sure there are other usages too. It will have been discussed on this list before. The GNU project's attitude to standards applies here: https://www.gnu.org/prep/standards/html_node/Non_002dGNU-Standards.html#Non_002dGNU-Standards "The GNU Project regards standards published by other organizations as suggestions, not orders. We consider those standards, but we do not “obey” them. " It is *practical* issues that we care about for versions of HTML, not what some standard demands or whatever is supposed to be "more modern".
