The Relax-NG schema for domains regarding <hostdev> doesn't match what's
implemented in src/conf/domain_conf.c#virDomainHostdevDefFormat(): The
implementation only requires @type, but the schema currently either
required none or all three attributes (@mode, @type, and @managed) to be
defined together, because they are declared in the same
<optional)-section. (@managed is currently even undocumented on
<http://libvirt.org/formatdomain.html#elementsUSB>).
Thus the following minimal <hostdev>-example fails to validate:
<domain type='test'>
<name>N</name>
<memory>4096</memory>
<bootloader>/bin/false</bootloader>
<os>
<type arch='x86_64' machine='xenpv'>linux</type>
</os>
<devices>
<hostdev type='pci'>
<source>
<address bus='0x06' slot='0x00' function='0x0'/>
</source>
</hostdev>
</devices>
</domain>
The schema is changed to match the current implementation:
1. @mode is optional (which defaults to 'subsystem')
2. @type is required
3. @managed is optional (which defaults to 'no')
The documentation is updated to mention @managed.
