The DR starts out talking about extensibility, then discusses the 
ability of "web services to evolve and adapt". It seems to me that 
extensibility applies to the architectural framework underlying XP - the 
ability to build upon XP in ways not explicitly specified by XP. 
Evolvability applies to specific uses of XP - the ability to modify an 
interface without prior agreement between communicating parties.

If the two terms are being used in these different contexts, should 
DR302 be split into two. If they are meant to be synonymous, I'd prefer 
the use of a single term.
