Well it is a little tricky to explain, but basically the expressions access 
content that is on another page, notably the home page. In order to be able 
to view this content from other pages in live mode, the content *on the 
home page* must have been validated before it can be used in other pages.

In the declaration, nothing is created except for a definition. This 
definition is attached to the template in which it was declared. Only when 
you start inserting elements in the container list are the objects created. 
You can retrieve instances of container lists through the absolute 
addressing mechanism for container lists (aka getAbsoluteContainerList)

Well if it's in the same template, the declaration will only happen once, 
but if it is in different templates, the declaration will be different 
since a definition is local to a template.

Gosh I really hope I can finish the template developer guide update soon, 
since a lot of this is already in there :(
