Yeah, XML prefix are something that makes documenting XML formats really hard. I started a discussion about this some months ago on the core docs, but Ryan and I can't find a good way to work with namespaces.

In the docs, I'm using the standard convetion for XML namespaces in Symfony2 projects. (the dashed bundlename).

The best option is to include the doctype + the root element (usually `<container>`) in all XML formats. It means that all code blocks work when copy/pasting (something Ryan likes) and it means that we can use some shorter prefix.
On the other hand, I think it makes code examples too complicated, too long and less readable.

I don't know what you think about this, but I agree that the prefixes should be shorter in the CMF docs, but I also think that we need to add a doctype + container element when doing that.
