+/**
+ @brief Mac policy module data
+
+ This structure specifies module data that is passed in to the
+ TrustedBSD MAC policy module by the kernel module loader. The
+ data is made of up key/value pairs where the key is always a
+ string and the value is a string, binary data or array. An array
+ may be a list of values (actually a similar set of key/value pairs,
+ but in this case the keys are always null), and may also consist of
+ a set of dictionaries, which in turn are made up of a list of key/value
+ pairs.
+
+ Module data may be specified in the MAC policy module's
+ Info.plist file as part of the OSModuleData dictionary.
+
+ E.g.
+
+ <key>OSModuleData</key>
+ <dict>
+ <key>foo</key>
+ <string>bar</string>
+ <key>Beers</key>
+ <array>
+ <dict>
+ <key>type</key>
+ <string>lager</string>
+ <key>Name</key>
+ <string>Anchor Steam</string>
+ </dict>
+ <dict>
+ <key>type</key>
+ <string>ale</string>
+ <key>Name</key>
+ <string>Sierra Nevada Pale Ale</string>
+ </dict>
+ </array>
+ </dict>
