[libvirt] [PATCHv2 1/6] schema: rewrite seclabel rng to match code
Eric Blake

Fri Dec 23 00:47:46 UTC 2011
The RNG for <seclabel> was too strict - if it was present, then it
had to have sub-elements, even if those didn't make sense for the
given attributes. Also, we didn't have any tests of <seclabel>
parsing or XML output.
In this patch, I added more parsing tests than output tests (since
the output populates and/or reorders fields not present in certain
inputs). Making the RNG reliable is a precursor to using <seclabel>
variants in more places in the XML in later patches.
