  - `#` character can be used to escape the parameter syntax. E.g. if the `parameterName` parameter's value is `xxx` then `#{parameterName}` will be replaced with `xxx`, `##{parameterName}` will be replaced with `#{parameterName}`, and `#####{parameterName}` will be replaced with `##xxx`.
  - Sensitive parameters can only be assigned to sensitive properties and non-sensitive parameters can only be assigned to non-sensitive properties.
 
+Parameter contexts can be inherited from multiple other parameter contexts. The order of the parameter inheritance matters in the way that if a parameter is present in multiple parameter contexts, the parameter value assigned to the first parameter in the inheritance order will be used. No circular inheritance is allowed.
