A recent thread on xen-devel [1] pointed out that the header was
provided as a reference for the specification.

Unfortunately, this was never written down in xen.git so for an external
user (or a reviewer) it is not clear whether the spec or the header
shoudl be followed when there is a conflict.

To avoid more confusion, a paragraph is added at the top of the header
to clearly spell out it is only provided for reference.
