+To take control over the sanitization, define a `SanitizingFunction` bean.
 The `SanitizableData` with which the function is called provides access to the key and value as well as the `PropertySource` from which they came.
 This allows you to, for example, sanitize every value that comes from a particular property source.
 Each `SanitizingFunction` is called in order until a function changes the value of the sanitizable data.
-If no function changes its value, the built-in key-based sanitization is performed.
