I've just been looking at a mail that got a hit on HTML_TAG_BALANCE_HEAD due to this:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/1999/REC-html401-19991224/loose.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head/> <body style="width: 800px"> I can't quite figure out whether the short tag syntax is allowed - the HTML above was generated by XSLT based on this input: <head></head> Other "popular" short tags: <br/> <div/> <p/> - I don't think we should be judging those to be unbalanced HTML tags. /Per Jessen, Zürich
