// This means we have the following domains :

// - Type Information for categorizing built in types as well as custom types
-// this includes information about enums, their values and names
-// - Type safe value storage : a kind of wxVariant, called right now wxxVariant

// - Property Information and Property Accessors providing access to a class'

// - Information about event handlers
