I had simplified the context of our framework, our model indeed does not
know anything about the observers. What it does(the model) is to trigger an
Announce, and then (via announcements mechanism) all the dependents get that
announce. The ugly part, is that we use blocks to "render the announcers"
and therefore we need to put the html inside the block, or inside the web

We will see if doing more hacking or just simply add the html is good for
As always, thanks for your quickly response.
