workaround ("...

validate=false:
mvn clean site -Dcheckstyle.ant.skip=true -DskipTests -DskipITs

Expected:
org.apache.xerces.parsers.SAXParser should be avoided . Doxia already removed
it from dependecies - https://issues.apache.org/jira/browse/DOXIA-526 , not
clear why "org.apache.xerces.parsers.SAXParser" is still referenced.
