Question on view node in maverick.xml

		<command name="welcome">
			<view path="welcome.jsp">
				<transform path="trimOutside.jsp"/>
			</view>
		</command>

I don't understand what the transform piece does in the view node above.  It seems to act like tiles sort of, if this is true then is there any reason to use the above syntax instead of tiles itself?

Thanks
