code: public static Condition createCondition( Element element ){
          if( element.countArguments() > 0 ){
              return new ExpressionLanguageCondition( element.getString( 0 ) );
          }
          else{
              return null;
          }
      }
docs: Creates a {@link Condition} based on the given conditional element. Supported types are
  {@link Type#IF}, {@link Type#ELSE_IF}, {@link Type#ELSE}, {@link Type#BRANCH}. The method
  works based on the fact that IF and ELSE_IF have exactly one argument, ELSE has no arguments,
  BRANCH has either zero or one arguments
