[Libvir] just a question about libvirt evolution

Hello, Several major modifications will appear this year in future Xen releases (3.0.3 and 3.0.4) that may have impacts on libvirt. These modifications (see xen roadmap edited by Ian Pratt in july 2006) are : - Introduction of XML-RPC, - Xen configuration files in XML format, - Suppression of S-Expressions, - etc.. What is the libvirt position about these points ? Is the initial goal of libvirt to mask Xen evolutions will be always possible ? The most problematic problem would be the configurations files in XML format. Libvirt already supports its own XML format of configuration files. It seems to me that it would be interesting to use the same XML format (or a compatible format) in libvirt and in Xen. Is there a plan in this direction ? Thanks.
