When Translation component tryes to load an invalid YAML file, you get

    InvalidResourceException: Error parsing YAML.
Which is not very helpful, I spent 1 hour looking for the invalid file, I think is better to include the file path in the exception message.

This adds validation on Process input. For the moment, passing a stream would result in a PHP error.
I propose to deprecate values that are not strictly string in 2.6 (see upcoming PR)
