AFAIK Michal removed the <choice> here a few days ago.

I don't think you need this bool, since the variable above is non-null
only in the correct cases and remains so until the end of the func when
you steal the value.

I think you will need to remember that the <auth> stuff was part of
<disk> and not source, since we can't change that. More on that in
review of the next patch.

This file is not used. See below for a comment I had on the same case
for RBD.

This file is added but not used in any test. Also when you are going to
make it used later, can't you just add another disk to an existing test
case? We have a few of cases which already test RBD auth. There's no
need to add so much of the bloat just to test the new syntax.

Do we really need both if the code paths in the parser are the same?
ACK with the test file stuff sorted out and the fix to the schema
change.
