... to specify a separate migration stream that will also be suitable for
live update.

The original scope of the document was to support non-cooperative migration
of guests [1] but, since then, live update of xenstored has been brought into
scope. Thus it makes more sense to define a separate image format for
serializing xenstore state that is suitable for both purposes.

The document has been limited to specifying a new image format. The mechanism
for acquiring the image for live update or migration is not covered as that
is more appropriately dealt with by a patch to docs/misc/xenstore.txt. It is
also expected that, when the first implementation of live update or migration
making use of this specification is committed, that the document is moved from
docs/designs into docs/specs.

Can we please add a general remark:

Records depending other records (e.g. watch records referencing a
connection record via a connection-id, or node records for a node
being a child of another node in the stream) must always be located
after the record they depend on.
