Subject: [PATCH] conf: Add XML parser flag that will allow us to do
7a3408
 incompatible updates
7a3408
7a3408
https://bugzilla.redhat.com/show_bug.cgi?id=1252685
7a3408
7a3408
Add a new parser flag that will mark code paths that parse XML files
7a3408
wich will not be used with existing VM state so that post parse
7a3408
callbacks can possibly do ABI incompatible changes if needed.
