[Radiant] scheduler extension + r:children:each

[Mark Gallop]

Hi all,

I have the scheduler extension installed and use the following code in a 
layout:

<r:find url="/news-and-events">
<r:children:each limit="5" order="desc" by="published_at">
<div class="entry">
  <h3><r:link /></h3>
  <p class="info">Posted <r:date format="%b %d, %Y" /></p>
</div>
</r:children:each>
</r:find>

Now this is showing links to pages which have expired as r:children:each 
ignores the expires_on value for the page.

I wonder if anyone can advise whether I would need to create my own tag 
to filter the children, or is it already possible to exclude expired 
pages using existing tags?

Cheers,
Mark
