title: how to suppress MyFaces console html warnings?
body: <p>We are getting ready to move our JSF 2 (MyFaces with Facelets pages) application to Production soon. Currently our console logs (SystemOut.log on WebSphere v8) are filling up with vast amounts of these kinds of messages:</p>

  <p>We feel this excessive logging may be hurting performance. While we understand that we should have coded our application propertly to html spec, it was delivered by an offshore vendor and we did not have as much control over the quality of the code as we'd like. At this point we probably don't have time to fix all the xhtml files (adding alt attribute to images, etc.).</p>
  
  <p>Is there any way we can disable this logging? For example a web.xml context param? I could not find anything in MyFaces documentation.</p>
