The current version does not use HTML constructs introduced after HTML 4.01 except for a custom attribute, as far as I can tell. So normally, simply setting the DOCTYPE and setting the customization variable that removes the custom attribute should be all you need to do, like texi2any --html -c DOCTYPE='<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd";>' -c 'NO_CUSTOM_HTML_ATTRIBUTE=1' myfile.texi Some attributes that were dropped in 4.01 strict and readded in HTML 5 may be present, though, but I am not very sure, and I think that they were still in the transitional HTML 4.01. -- Pat
