title: Error with faces-config.xml and primefaces-sentinel.taglib.xml when using primefaces premium theme
body: <p>I am using a Primefaces Premium theme I added the necessary jars to its classpath but encountered an error I could not debug because it seems to be not java related but xml/jsf related</p>
  
  <p><strong>faces-config.xml</strong></p>
