We are running Tapestry 5.2.6 in production and I'd like to be able to add 
content to the <head> html area from components other than the main page layout 
container. For example, a particular page component might need to populate a 
<meta> element, or even change the page title or add an additional css file.

In Rails you have <% yield %> as a way of doing this, and it is very helpful.

Is there a similar approach? I'm not thinking of defining all this in Java and 
passing parameters back and forth between components and containers; I need 
something more flexible.

Thanks
Ari
