I built a [Parental Control for iOS](http://mocava.de/ios/parental-control). In the background, it simply generates configuration profiles which users can then install to enforce or relax restrictions on the device.

In the settings app of iOS, there is a restriction which prevents users from removing apps (see Settings -> General-> Restrictions-> Delete apps). 
However I can't find the corresponding flag in the [documentation](http://developer.apple.com/library/ios/#featuredarticles/iPhoneConfigurationProfileRef/Introduction/Introduction.html) of the configuration profile. Does anyone know whether this flag is just not exposed or I missed something?
