I actually started out with this in the virCaps structure, but there was one
problem with that; at virDomainDefFree time, the caps pointer is *not* passed
in (nor is it stored in the virDomainDef structure), so you can't call the
namespace-specific free function. So it was a choice between modifying all of
the callers of virDomainDefFree to pass in the virCaps structure, or modifying all
of the callers of the virDomainDefParse* to pass in the struct xmlNamespace callback
structure. I chose the latter because logically the namespaceData does belong in
the virDomainDef structure, since it is part of the XML.
