One more point about extensions.  As far as I can remember, the term 
originated with the language (COBOL, Fortran, etc.) standards and was used 
in the context of implementer and programmer conformance where an 
implementer conformed if implementations contained extensions (the standard 
being a floor for implementers) but the programmer did not conform if 
he/she used the extensions provided by the implementation (the standard is 
a ceiling for programmers).  If the word gradually broadened over the years 
to sometimes include other things, I think that's a poor use of the 
term.  By writing our documents and defining terms we have the opportunity 
to force precision in writing and speaking.
