// All <dict> elements from the plist XML must be ordered (alphabetically sorted) by their key names. Use
// a recursive method to apply ordering also to nested dictionaries contained in the root-level dictionary
// and in arrays. Use non-localized (culture invariant), non-ASCII value based case insensitive ordering.
// For example the key <key>allowWlan</key> comes before <key>allowWLAN</key>. Cocoa/Obj-C and .NET/C#
// usually use this case insensitive ordering as default, but PHP for example doesn't.
