I think that the word "deprecated" should be deleted.  Unless it is really 
a key part of the definition that a feature can only be defined to be 
"obsolete" if it has first been "deprecated".  If that is *not* a key part 
of the definition, you could add a second sentence about relationship to 
deprecated:  "A feature is often deprecated before becoming obsolete."

Ed comment.  Change "It is not applicable if there is no obsolete 
features." to "This checkpoint is not applicable if there are no obsolete 
features."
