Noah's comments on Versioning strategies

Noah wrote up 4 pages of comments on the versioning strategies document, which he then photographed, gave to me in digital form and
I have gone through.  
 
I've done basically all the changes suggested, except for the following.
 
1. Language vs Language specification.  
We continue to disagree about whether to use Language or language specification.  While I do think I agree that using language
specification instead of language in many cases may be more precise, I believe that extra term clutters and degrades the
approachability of our document.  For example, I prefer "are processable by software that is written the older version(s) of the
language," to your variant of "are processable by software written to the older specification(s) of the language".
 
I couldn't read the comment on 
1., bullet #2 2nd comment
