Symfony 2 download xml validation package

Question

How to import a validation.xml file into a project?

Because now it just seems ignored and not loaded.

I tried:

- { resource: "@GvnSnippetryBundle/Resources/config/validation.xml" } 

But that did not work. I did not find any information about this. It seems like it should load automatically. But this is not so.

Answer 1

I explored this at the bottom. The validation.xml file is loaded, but it is not used with the cache (even in developer mode).
