New subject: [PATCH 1/2] capabilityschemadata: Fix order of <features/> in caps-test2.xml
The guest <features/> is formatted in
virCapabilitiesFormatGuestFeatures() and the order in which
individual child elements are formatted is fixed, because the
function iterates over the virCapsGuestFeatureType enum
(possibly) formatting each member until _LAST is met.
Therefore, <cpuselection/> and <deviceboot/> can't ever be
formatted first. Move these elements to proper location.

New subject: [PATCH 2/2] schemas: Drop <interleave/> from capabilities schemas
Currently, we have two types of output only XMLs: capabilities
and domaincapabilities. Neither of these is ever parsed.
Moreover, the order of elements inside these two documents is
well defined by their respective format functions. Therefore,
there's no need to have <interleave/> anywhere in their
corresponding schemas.

How confident can we be that we've never changed the order of
any elements ? IMHO its best practice to always use <interleave/>

The consumers of libvirt need to parse the XML, and they may wish

ever, or will ever, change ordering of elements, our RNG should
be prepared for that. IOW, we should consider the RNG to be something

Well, that's a very strong requirement that we don't even have for
domain XML. I though that using RNG from corresponding libvirt release
is recommended.
How confident can we be that we've never changed the order of
any elements ? IMHO its best practice to always use <interleave/>
We're currently only halfway there. Some elements are allowed to
interleave, some aren't. But okay, let's drop my patches and if we ever
decide to change ordering we'll have domaincapstest, well virschematest
shouting at us.
