Renders the tag contents only if the contents do not match the previous header. This

is extremely useful for rendering date headers for a list of child pages.

If you would like to use several header blocks you may use the @name@ attribute to

name the header. When a header is named it will not restart until another header of

the same name is different.

Using the @restart@ attribute you can cause other named headers to restart when the

present header changes. Simply specify the names of the other headers in a semicolon
-
separated list.

-

<pre><code><r:children:each>
