The JTidyServlet project (mentioned in various answers) appears to be more or less defunct -- no browsable source, no downloads linked from the SourceForge project page apart from the main JTidy download (which doesn't include the servlet or filter), no Maven artifacts in any repositories I can find. Can anyone recommend a more up-to-date alternative?

Looks like there's some source code here; https://github.com/vnc-biz/zcs-lib-jtidy/

For aesthetics' sake -though admittedly pointless- I too recently have striven to deliver visually appealing HTML5 source originating from JSF (alongside with PrimeFaces) Facelets to user agents.

JTidy and its accompanying utils didn't really help me out; it radically attempted to "fix" my "broken" markup, e.g. by switching DTD and modifying various elements (as if there is such a thing as valid HTML in the real world anyway). XSLT would be a satisfying alternative, were the application/xhtml+xml Content-Type to be used (similarly in an ideal world). Then I stumbled upon jsoup and after a few attempts, combining its API with examples obtained from [3], [4], [5], [6], [7], the result was quite a surprise:

No "well-thought-out XMLization" changes whatsoever (self-closing <script>s, <![CDATA[s, etc.), just line breaks and indentation. Of course the output remains XHTML invalid, but that shouldn't be an issue for the average browser. Lastly, I don't know if the outcome would be as positive in the case of a full-fledged Facelet.
