eXo Platform allows you to enable/disable auto-creating a taxonomy tree during a new site creation by adding the
    ecms.taxonomy.autoCreateWithNewSite parameter to the following files. 
	See Configuration overview for how-to.
				$PLATFORM_TOMCAT_HOME/gatein/conf/exo.properties (Tomcat).
			
				$PLATFORM_JBOSS_HOME/standalone/configuration/gatein/exo.properties (JBoss).
			
# Configuration for a taxonomy tree
ecms.taxonomy.autoCreateWithNewSite=false
    By default, the parameter is set to false, it means the creation of a taxonomy tree is disabled
    when you create a new site.
  
To enable the function, simply set the parameter to true.
