What does ~ mean in the YML configuration file in Symfony 2?

Question

For example:

NotBlank: ~

This question is similar to: What is the purpose of tilde character ~ in YAML?. If you believe it’s different, please edit the question, make it clear how it’s different and/or how the answers on that question are not helpful for your problem. — Nico Haase

In Yaml, ~ means null.

The actual meaning in Symfony 2 depends on what you are configuring. Most likely it will mean "use defaults" or it will be used where it is needed to put a configuration key but there is nothing to actually configure for that key (as in the NotBlank example).
