The numbers aren't referenced directly, and explicit numbering makes an
unnecesserily large diff when inserting something new in the middle.

 There are some strict ordering requirements.  The following records must
 be present in the following order as each of them depends on information
 present in the preceding ones.

 x86 HVM Guest

 A typical save record for an x86 HVM guest image would look like:
 
-1. Image header
-2. Domain header
-3. Many PAGE_DATA records
-4. TSC_INFO
-5. HVM_PARAMS
-6. HVM_CONTEXT
+* Image header
+* Domain header

 HVM_PARAMS must precede HVM_CONTEXT, as certain parameters can affect
 the validity of architectural state in the context.
