docs: Get whether the specified I{node} is a soap encoded root.
          This is determined by examining @soapenc:root='1'.
          The node is considered to be a root when the attribute
          is not specified.
          @param node: A node to evaluate.
          @type node: L{Element}
          @return: True if a soap encoded root.
          @rtype: bool
