[Invalid] Markup Validation of https://wiki.python.org/jython/UserGuide - W3C Markup Validator

For the current document, the validator interprets strings like <FOO /> according to legacy rules that break the expectations of most authors and thus cause confusing warnings and error messages from the validator. This interpretation is triggered by HTML 4 documents or other SGML-based HTML documents. To avoid the messages, simply remove the "/" character in such contexts. NB: If you expect <FOO /> to be interpreted as an XML-compatible "self-closing" tag, then you need to use XHTML or HTML5.
