Notice that the DOCTYPE in the preceding screenshot specifically calls out Apple, and settings are structured with no particular ordering since it has a hash or dict (short for dictionary) as the base type. The following screenshot has more details on this 802.1x-specific configuration:

A Wi-Fi configuration profile, which would tell the radius controller that Active Directory credentials will be used for 802.1x authentication

There is, however, no concept of binding an iOS device to a directory service, nor of different users having customized settings, whereas Macs can take both into account. Products even exist to manage settings for Macs within the same interface as GPO for PCs. For iOS though, the MDM service itself needs to be aware of the groupings and management settings which it can then act upon to hand down configurations to devices. This is in contrast to Macs, which can even be told to provide authentication to radius controllers over Wi-Fi with Active Directory credentials at the login window, as shown in the preceding screenshot. If you deployed the profile pictured previously to an iOS device, it may very well ignore the unused options or fail altogether.

Now that we have seen more about the format and how it's scoped to devices, let's look into the history of this management format. Apple's canonical reference of an interface with which to construct the settings available for managing iOS devices first appeared in a tool for Windows and Mac called iPhone Configuration Utility (or iPCU for short, which makes it sound like one of those places you can get an associate's degree on the internet). It was originally released back when the OS was called iPhone OS 2. (Really, it was OS/2 Warp. Now that was an OS!) When constructing a configuration profile, you would see management options grouped into sections in a sidebar on the left, and you would interact with various fields on the right. The following screenshot shows the configuration profile creation/editing in the iPCU interface:
