+/**
+ * ConfigurableRequirementsInterface must be implemented by URL generators that
+ * can be configured whether an exception should be generated when the parameters
+ * do not match the requirements. It is also possible to disable the requirements
+ * check for URL generation completely.
+ *
+ * The possible configurations and use-cases:
+ * - setStrictRequirements(true): Throw an exception for mismatching requirements. This
+ *   is mostly useful in development environment.
+ * - setStrictRequirements(false): Don't throw an exception but return null as URL for
+ *   mismatching requirements and log the problem. Useful when you cannot control all
+ *   params because they come from third party libs but don't want to have a 404 in
+ *   production environment. It should log the mismatch so one can review it.
+ * - setStrictRequirements(null): Return the URL with the given parameters without
+ *   checking the requirements at all. When generating an URL you should either trust
+ *   your params or you validated them beforehand because otherwise it would break your
+ *   link anyway. So in production environment you should know that params always pass
+ *   the requirements. Thus this option allows to disable the check on URL generation for
+ *   performance reasons (saving a preg_match for each requirement every time a URL is
+ *   generated).
