[PATCH 07/12] schema: Introduce scaffolding for schema for <privateData> elements
Libvirt internally (e.g. in the status XML) stores additional data for
various objects described by the XML. The data is usually stored in
<privateData> or similar sub-elements.
This patch adds possibility for internal schema files to describe the
<privateData> elements by schema while still disallowing them for the
public schema.
This patch adds definitions for private data of <disk> and the
corresponding storage source of a disk.
