Sorry, this is one bit I'm still stuck on... ;) Where did you [as the reader] define the id parameter?

Looking at [the original](https://github.com/symfony-cmf/symfony-cmf-docs/blob/master/getting-started/routing.rst#the-phpcr-odm-route-document), I can see a call to `$route->setRouteContent($content)` but not sure where the id comes in? Do we need to tweak the sample code?

On another note, there are a few mentions of the PHPCR-ODM route provider, but I am having trouble finding this in the code...?
