 /**
  * A structure field description.
+ *
+ * @todo Add an type field here for recording what's a GCPtr, GCPhys or anything
+ *       else that may change and is expected to continue to work.
+ * @todo Later we need to add load transformations to this structure. I think a
+ *       callback with a number of default transformations in SIG_DEF style
+ *       would be good enough. The callback would take a user context from a new
+ *       SSMR3GetStruct parameter or something.
