2	* Settings file data structures.
3	*
4	* These structures are created by the settings file loader and filled with values
5	* copied from the raw XML data. This was all new with VirtualBox 3.1 and allows us
6	* to finally make the XML reader version-independent and read VirtualBox XML files
7	* from earlier and even newer (future) versions without requiring complicated,
8	* tedious and error-prone XSLT conversions.
9	*
10	* It is this file that defines all structures that map VirtualBox global and
11	* machine settings to XML files. These structures are used by the rest of Main,
12	* even though this header file does not require anything else in Main.
13	*
14	* Note: Headers in Main code have been tweaked to only declare the structures
15	* defined here so that this header need only be included from code files that
16	* actually use these structures.
