This patch is my first experience playing with nested grammars, as documented in http://relaxng.org/tutorial-20011203.html#IDA3PZR. I plan on doing more overrides in order to make the RelaxNG grammar mirror the C code refactoring into a common virStorageSource, but where different clients of that source do not support the same subset of functionality. By starting with something fairly easy to validate, I can make sure my later patches will be possible. This patch adds a use of the no-op <ref name='sourceStartupPolicy'/> to the disksnapshot definition, so that the snapshot version of a type='file' <source> more closely resembles the version in domaincommon. A future patch will merge the two files into using a common define, but this patch is sufficient for testing that adding <source startupPolicy='optional'/> in any of the tests/domainsnapshotxml2xmlin/*.xml files still gets rejected unless it occurs within the <domain> subelement, because the definition of startupPolicy is empty outside of domain.rng. * docs/schemas/storagecommon.rng (storageStartupPolicy) (storageSourceExtra): Create no-op defaults. * docs/schemas/domainsnapshot.rng (domain): Use nested grammar to avoid restricting <domain>. (storageSourceExtra): Create new override. (disksnapshot): Access overrides through common names. * docs/schemas/domaincommon.rng (disk): Access overrides through common names. * docs/schemas/domain.rng (storageStartupPolicy) (storageSourceExtra): Create new overrides.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
