desc %{
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.
*Usage:*
<pre><code><r:children:each>
<r:header [name="header_name"] [restart="name1[;name2;...]"]>
...
</r:header>

Renders the main content of a page. Use the @part@ attribute to select a specific

attribute to specify that if a page does not have a content part by that name that
the tag should render the parent's content part. By default @inherit@ is set to
@false@. Use the @contextual@ attribute to force a part inherited from a parent
part to be evaluated in the context of the child page. By default 'contextual'

Renders the containing elements if all of the listed parts exist on a page.
By default the @part@ attribute is set to @body@, but you may list more than one
part by separating them with a comma. Setting the optional @inherit@ to true will
search ancestors independently for each part. By default @inherit@ is set to @false@.
When listing more than one part, you may optionally set the @find@ attribute to @any@

Renders the date based on the current page (by default when it was published or created).
The format attribute uses the same formating codes used by the Ruby @strftime@ function.
