The XML allows <encryption format='unencrypted'/>, this implementation
canonicalizes the internal representation so that "disk->encryption" is
non-NULL iff encryption information is available.
A domain with partial encryption information can be defined,
completeness of the information is not verified. The domain won't
start until the remaining information is added, of course.
Changes since the second submission:
- Mark <encryption> as <optional> in the schema
- Drop <encryption format='unencrypted'/>
