Added config fixtures in each format to demonstrate the possible styles of all of the extension options. These should all be covered by the updated tests. Made XSD slightly more restrictive, with regards to the "type" attribute on globals. This is coupled with validation in the configuration class.
How to upgrade?
For XML configuration files:
* All extensions should now use the config tag (this is just a convention as
the YAML configurations files do not use it anymore):
* The previous change means that the doctrine and security bundles now are
wrapped under a main "config" tag:
<doctrine:config>
<doctrine:orm />
<doctrine:dbal />
</doctrine:config>
<security:config>
<security:acl />
...
</security:config>
For YAML configuration files:
* The main keys have been renamed as follows:
* assetic:config -> assetic
* app:config -> framework
* webprofiler:config -> web_profiler
* doctrine_odm.mongodb -> doctrine_mongo_db
* doctrine:orm -> doctrine: { orm: ... }
* doctrine:dbal -> doctrine: { dbal: ... }
* security:config -> security
* security:acl -> security: { acl: ... }
* twig.config -> twig
* zend.config -> zend
A global can now be a service or a string:
<twig:config debug="%kernel.debug%" strict-variables="%kernel.debug%">
<twig:global key="request" type="service" id="request" />
<twig:global key="PI">3.14</twig:global>
</twig:config>
For existing Symfony2 applications, references to Symfony\Framework are found
in the main Kernel class (registerBundles() and registerBundleDirs()), and in
all Controller classes. You also need to change the console script.
