		<p>In the first notify-call the listener gets two(!)
		<type scope="com::sun::star::sdbc">XResultSet</type>s and has to hold
        them. The <type scope="com::sun::star::sdbc">XResultSet</type>s are
        implementations of the service <type>ContentResultSet</type>.

		<p>The notified new 
        <type scope="com::sun::star::sdbc">XResultSet</type> will stay valid
        after returning from this method. The old one will become invalid after
		returning.

		<p>While in notify-call the listener is allowed to read from old and
		new	resultset, except in the first call, where only the new resultset
		is valid.

		<p>The Listener is allowed to stay (block) this call, until he really
		wants to use the new resultset. The only situation, where the listener
		has to return immediately is while he disposes his broadcaster or while
		he is removing himself as listener (otherwise you deadlock)!!!

		@param  Changes
		the changes to notify.
