A specific example would be the value of an ID/IDREF.  So long as the 
values are consistent from a referential integrity perspective, an 
implementation should be able to freely rewrite these values with 
application-generated unique random identifiers.  There are examples of 
values that may change, but typically are not of interest to a user from a 
change-tracking perspective.
