Differences between required_features and permissions?

Marcos,

What is the major difference between required_features and permissions? Only is that permissions is a localizable member? Can we merge them into one member and let's Runtime implementation to translate the required features into localization string in this sense every web app could have consistent localization message if prompting permissions confirmation.

In addition, the naming convention should be 'require_features'. It should be 'requiredFeatures' or 'features', right?


Thanks
