In Magento2 2.0.0, it change xml schema validation. It using URN schema validation.

You can read more at http://devdocs.magento.com/guides/v2.0/extension-dev-guide/XSD-XML-validation.html

You have to create my own config file with it's own validation schema?

You can read at Magento 2 custom xml schema validation

In di.xml file, you need change to:

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
....
<config>
