Re: [libvirt] [PATCHv2 1/9] conf: better <disk> interleaving in schema

In general, we try to make virt-xml-validate tolerant of input elements in any order when possible. However, as written, the RNG grammar did not permit <source> unless there was an explicit type= attribute (even though the C code manages just fine by defaulting to type='file'). After making the attribute optional on the 'file' branch, I noticed that the use of diskspec was now redundant with the branch when no <source> was supplied. View this patch with 'git diff -b' for a better picture of the schema change.
