+ Though it won't disable explicit geo restriction bypass based on
+ country code provided with geo_bypass_country. (experimental)
+
+ _GEO_COUNTRIES attribute may contain a list of presumably geo unrestricted
+ countries for this extractor. One of these countries will be used by
+ geo restriction bypass mechanism right away in order to bypass
+ geo restriction, of course, if the mechanism is not disabled. (experimental)
+
+ NB: both these geo attributes are experimental and may change in future
+ or be completely removed.
+
Finally, the _WORKING attribute should be set to False for broken IEs
in order to warn the users and skip the tests.
