Permission check inconsistency

[PhilBau]

Hi,
if you look at lib/Feeds/Version.php, you read:
$meta['securityschema'] = array('Feeds::Item' => 'Feed item name::Feed item ID');

But in the code, I see:
lib/Feeds/Block/Displayfeed.php:43: ...SecurityUtil::checkPermission('Feeds:NewsFeed:', "$blockinfo[title]::",... ACCESS_READ
lib/Feeds/Api/User.php:36: ...SecurityUtil::checkPermission( 'Feeds::', '::', ACCESS_READ...
...

So, what is the correct permission scheme?
