Subject: [PATCH] storage: allow interleave in volume XML
c401cc
c401cc
https://bugzilla.redhat.com/show_bug.cgi?id=1032370
c401cc
c401cc
The RNG grammar did not allow arbitrary interleaving, which makes
c401cc
it harder than necessary to create a new volume from handwritten XML.
c401cc
(Compare also to commit caf516db for pools).
c401cc
c401cc
* docs/schemas/storagevol.rng: Support interleaving.
c401cc
* tests/storagevolxml2xmlin/vol-file-backing.xml: Test it.
