--- Comment #8 from Remi Collet fedora@famillecollet.com --- So for late error detection
DependencyInjection/Loader/schema/dic/services/services-1.0.xsd should be installed as role="php", not as role="doc" as this path is referred in the code
In DependencyInjection/Loader/XmlFileLoader.php
$schemaLocations = array('http://symfony.com/schema/dic/services' => str_replace('\', '/', __DIR__.'/schema/dic/services/services-1.0.xsd'));
Like for "Locale" this should be reported upstream, and role="data" is probably a better solution.
