Root element

An IzPack installation description must be always embedded into the root element <installation>.

Parameters:

version	The attribute defines the version of the XML file layout and is used by the compiler to identify if it is capable of compiling the XML file correctly.

For izPack version 5.0.0-rc1, use version="5.0"	yes
